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. -

Converged?" • Occasionally You May Run Into Situations Where Common Physical Infrastructure Serves Multiple Purposes
The Inescapable Inevitability of Convergence (Unless You "Help") Converging Campus Technologies: Evolution or Intelligent Re-Design? NWACC 2006 Annual Conference Portland, Oregon, June 9th, 2006 Joe St Sauver, Ph.D. ([email protected]) Director, User Services and Network Applications University of Oregon Computing Center http://www.uoregon.edu/~joe/convergence/ Introduction • Welcome to the last session for this year's NWACC conference. I'd like to thank Marty for the opportunity to present this session, and I hope you've all enjoyed the rest of this year's meeting as much as I have. • It's rare for me to have a talk theme mesh so well with the overall theme of an event, or so closely with the major news events of the day, but I think that may be fortunate since I'm all that's between you and lunch (or a few hours of exploring Portland before heading home). I'll try to make sure you get your money's worth for the time you're investing. 2 Format of This Session/Handout • This session will be a half hour introduction/ overview followed by up to an hour for discussion. • While I'll begin by presenting one perspective on convergence, mine,* I hope you'll feel free to share your perspective during the discussion period, particularly if you see things differently than I do. • A note about this handout: I tend to cover a lot of material, so to help me stay on track, to facilitate later review by folks not here with us today, and to accommodate attendees who may be hearing impaired, I've scripted these slides in some detail (think of them as "closed captioning"). -
A Review Paper on Microwave Transmission Using Reflector Antennas
International Journal of Scientific & Engineering Research Volume 8, Issue 10, October-2017 ISSN 2229-5518 251 A Review Paper on Microwave Transmission using Reflector Antennas Sandeep Kumar Singh [1],Sumi Kumari[2] Sr. Lecturer, Dept. of ECE, JBIT, Dehradun [1], Asst. Professor, Dept. of ECE, VGIET, Jaipur[2] [email protected][1] [email protected][2] Abstract: The conventional optimization problem of the beamed microwave energy transmission system is considered. The criterion of maximum efficiency of power intercept is parabolic function of distribution on the transmitting antenna. It is shown that under such a condition of amplitude distribution becomes more uniform than as the unconditional optimization. In this case, we can substantially increase the power radiated by the transmitting antenna losing the power intercept no more than 2%. Keywords: Parabolic Reflector Antenna, Radio Relay, Antenna Gain, Cassegrain Feed. I.INTRODUCTION limited to line of sight propagation; they cannot pass around hills or mountains as lower frequency radio waves can. Microwave radiation is generally defined as that electromagnetic radiation having wavelengths between radio waves and infrared III.ANTENNA radiation. Microwave radiation can be forced to travel in specially designed waveguides. Microwave radiation can be transmitted An antenna (or aerial) is an electrical device which converts through space or through the atmosphere in a microwave beam electric currents into radio waves, and vice versa. It is usually used from a microwave antenna and the microwave energy can be with a radio transmitter or radio receiver. In transmission, a radio collected with a microwave antenna. Microwave antennas are used transmitter applies an oscillating radio frequency electric current to for transmitting and receiving microwave radiation. -

Design and Construction of a Cost-Effective Parabolic Satellite Dish Using Available Local Materials
International Journal of Advanced Materials Research Vol. 5, No. 3, 2019, pp. 46-52 http://www.aiscience.org/journal/ijamr ISSN: 2381-6805 (Print); ISSN: 2381-6813 (Online) Design and Construction of a Cost-effective Parabolic Satellite Dish Using Available Local Materials Gbadamosi Ramoni Adewale * Faculty of Science, National Open University of Nigeria, Akure, Nigeria Abstract Communication through satellite is very important at this information age. It can provide complete global coverage. It can be used to send and receive information in remote area where other technology may fail. Communication signals are sent in form of electromagnetic signal which are intercepted by the parabolic dish. The offered high-efficiency and high-gain by the parabolic dish makes it appropriate for direct broadcast satellite reception. However, parabolic dish procurement in developing countries is very expensive. This makes it to be unaffordable to majority of the masses. This paper focuses on design and construction of cheap parabolic satellite dish using local readily available materials. An indigenous technology is exploited to achieve the goal of this work. The paper describes from the scratch, how to design and construct a parabolic dish that can be used to intercept electromagnetic signals from the satellite stationed in the space. The proposed design approach offers a number of advantages such as cost-effectiveness and high simplicity. These are due to the fact that; it can be effectively developed with the easily available materials. Besides, it development demands neither special/long time training nor skill. Thus, both technical and non-technical personnel with minimal training can construct it either for commercial and/or personal use. -
