Among the most prevalent antennas, Yagi-Uda antenna is widely used. To improve the antenna gain and directivity, design of antenna is always important. In this paper, the Yagi Uda antenna is modified by adding two more reflectors instead of single and the gain, directivity & radiation pattern were studied. This antenna is designed to give better gain in one particular direction as well as somewhat reduced gain in other directions. The direction of "reduced gain" and gain at particular direction are not controllable in Yagi Uda. This paper provides a design which modifies radiation pattern of Yagi as per user requirement. The experiment is carried out at 157 MHz and all readings are taken for vertical polarization, with the help of Radio Communication Monitor. Keywords: Wireless communication, Yagi-Uda, Communication Service Monitor, Vertical polarization. 1 Introduction three) are used.

That assumption allowed us to say that the current in the antenna was independent of position along the antenna, depending only on time: I(t) = I0 cos(t) no z dependence! For longer antennas, this is no longer true.

  • WDP.2458.25.4.B.02 Linear Polarization Wifi Dual Bands Patch
    SPECIFICATION PATENT PENDING Part No. : WDP.2458.25.4.B.02 Product Name : Wi-Fi Dual-band 2.4/5 GHz Embedded Ceramic Patch Antenna 6dBi+ at 2.4GHz 6dBi+ on 5 to 6 GHz Features : 25mm*25mm*4mm 2400MHz to 2500MHz/5150MHz to 5850MHz Pin Type Supports IEEE 802.11 Dual-band Wi-Fi systems Dual linear polarization Tuned for 70x70mm ground plane RoHS & REACH Compliant SPE-14-8-039/B/WY Page 1 of 14 1. Introduction This unique patent pending high gain, high efficiency embedded ceramic patch antenna is designed for professional Wi-Fi dual-band IEEE 802.11 applications. It is mounted via pin and double-sided adhesive. The passive patch offers stable high gain response from 4 dBi to 6dBi on the 2.4GHz band and from 5dBi to 8dBi on the 5 ~6 GHz band. Efficiency values are impressive also across the bands with on average 60%+. The WDP.25’s high gain, high efficiency performance is the perfect solution for directional dual-band WiFi application which need long range but which want to use small compact embedded antennas. The much higher gain and efficiency of the WDP.25 over smaller less efficient more omni-directional chip antennas (these typically have no more than 2dBi gain, 30% efficiencies) means it can deliver much longer range over a wide sector. Typical applications are • Access Points • Tablets • High definition high throughput video streaming routers • High data MIMO bandwidth routers • Automotive • Home and industrial in-wall WiFi automation • Drones/Quad-copters • UAV • Long range WiFi remote control applications The WDP patch antenna has two distinct linear polarizations, on the 2.4 and 5GHz bands, increasing isolation between bands.

  • Executive Summary of the ICAO Position for ITU WRC-15 Radio
    Executive Summary of the ICAO Position for ITU WRC-15 Radio frequency spectrum is a scarce natural resource with finite capacity for which demand is constantly increasing. The requirements of civil aviation as well as other spectrum users continue to grow at a fast pace, thus creating an ever-increasing pressure to an already stretched resource. International competition between radio services obliges all spectrum users, aeronautical and non- aeronautical alike, to continually defend and justify retention of existing or addition of new frequency bands. The ICAO Position aims at protecting aeronautical frequency spectrum for all radiocommunication and radionavigation systems used for ground facilities and on board aircraft. The ICAO Position addresses all radioregulatory aspects on aeronautical matters on the agenda for the WRC-15. The items of main concern to aviation include the following: identification of additional frequency bands for the International Mobile Telecommunications (IMT). Under this agenda item, the telecommunications industry is seeking up to 1200 MHz of additional spectrum in the 300 MHz to 6 GHz range for mobile and broadband applications. It is expected that a number of aeronautical frequency bands will come under pressure for potential repurposing, especially some of the Primary Surveillance Radar (PSR) bands. Existing frequency allocations which are vital for the operation of aeronautical very small aperture terminal (VSAT) ground-ground communication networks, especially in tropical regions, are also expected to come under pressure. Due to decisions made by a previous WRC, this has already become a problematic issue in Africa. WRC-15 agenda items 1.1 and 9.1.5 refer; potential radioregulatory means to facilitate the use of non-safety satellite service frequency bands for a very safety-critical application, the command and control link for remotely piloted aircraft systems (RPAS) in non-segregated airspace.

  • Development of Earth Station Receiving Antenna and Digital Filter Design Analysis for C-Band VSAT
    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 3, ISSUE 6, JUNE 2014 ISSN 2277-8616 Development of Earth Station Receiving Antenna and Digital Filter Design Analysis for C-Band VSAT Su Mon Aye, Zaw Min Naing, Chaw Myat New, Hla Myo Tun Abstract: This paper describes the performance improvement of C-band VSAT receiving antenna. In this work, the gain and efficiency of C-band VSAT have been evaluated and then the reflector design is developed with the help of ICARA and MATLAB environment. The proposed design meets the good result of antenna gain and efficiency. The typical gain of prime focus parabolic reflector antenna is 30 dB to 40dB. And the efficiency is 60% to 80% with the good antenna design. By comparing with the typical values, the proposed C-band VSAT antenna design is well optimized with gain of 38dB and efficiency of 78%. In this paper, the better design with compromise gain performance of VSAT receiving parabolic antenna using ICARA software tool and the calculation of C-band downlink path loss is also described. The particular prime focus parabolic reflector antenna is applied for this application and gain of antenna, radiation pattern with far field, near field and the optimized antenna efficiency is also developed. The objective of this paper is to design the downlink receiving antenna of VSAT satellite ground segment with excellent gain and overall antenna efficiency. The filter design analysis is base on Kaiser window method and the simulation results are also presented in this paper. Index Terms: prime focus parabolic reflector antenna, satellite, efficiency, gain, path loss, VSAT.

  • Design and Application of a New Planar Balun
    DESIGN AND APPLICATION OF A NEW PLANAR BALUN Younes Mohamed Thesis Prepared for the Degree of MASTER OF SCIENCE UNIVERSITY OF NORTH TEXAS May 2014 APPROVED: Shengli Fu, Major Professor and Interim Chair of the Department of Electrical Engineering Hualiang Zhang, Co-Major Professor Hyoung Soo Kim, Committee Member Costas Tsatsoulis, Dean of the College of Engineering Mark Wardell, Dean of the Toulouse Graduate School Mohamed, Younes. Design and Application of a New Planar Balun. Master of Science (Electrical Engineering), May 2014, 41 pp., 2 tables, 29 figures, references, 21 titles. The baluns are the key components in balanced circuits such balanced mixers, frequency multipliers, push–pull amplifiers, and antennas. Most of these applications have become more integrated which demands the baluns to be in compact size and low cost. In this thesis, a new approach about the design of planar balun is presented where the 4-port symmetrical network with one port terminated by open circuit is first analyzed by using even- and odd-mode excitations. With full design equations, the proposed balun presents perfect balanced output and good input matching and the measurement results make a good agreement with the simulations. Second, Yagi-Uda antenna is also introduced as an entry to fully understand the quasi-Yagi antenna. Both of the antennas have the same design requirements and present the radiation properties. The arrangement of the antenna’s elements and the end-fire radiation property of the antenna have been presented. Finally, the quasi-Yagi antenna is used as an application of the balun where the proposed balun is employed to feed a quasi-Yagi antenna.

SW 6050.12A CHANGE SUPPLEMENTS OPTIONAL CHANGE SUPPLEMENTS OPTIONAL TO TO BASIC BASIC 12/12/01 SW 6050.12A FOREWORD The radio frequency spectrum is a finite, vital, and very limited natural resource available to all countries of the world. This international resource serves mankind in innumerable ways, and each country exercises its own sovereign rights in the use of the electromagnetic waves. Because the radio spectrum knows no bounds, its use cannot be restricted to individual countries. Requirements for use of this resource generally exceed the amount available; therefore, it is necessary that international, national, and regional spectrum management be rigidly practiced. The purpose of this spectrum management order is to present radio frequency spectrum information, guidance, and policy to those organizations using or administrating the radio frequency spectrum within the Southwest Region.
