2017 Gnss Antenna Survey Brought to you by 2017 GNSS ANTENNA SURVEY After choosing the most appropriate receiver for your application from the Receiver Survey in the January issue of GPS World, you may need an antenna, too. We have collected key specifications for 377 antennas from 31 manufacturers. We publish the Antenna Survey each year in our February issue. To recommend improvements or to be listed in the survey next year, please email [email protected].

These key performances features combined with a low profile Positioning Starts at the patch antenna are suited for ground vehicle applications in agriculture, machine control, and mobile mapping. GNSS Antenna GNSS-800 SERIES A common misconception in the marketplace is that the GNSS antenna is a peripheral component of a GNSS system.

This research is focused on implementing vehicle-to-vehicle and vehicle-to-infrastructure communications to advance both the safety and the quality of the driving experience of modern motorists. This thesis achieves three separate goals. First, a brief literature review details the current state of DSRC antenna research and the drawbacks of antenna designs previously presented. Secondly, several common wire antennas are modeled and simulated in order to assess their potential in DSRC communications. Using an industry standard electromagnetic full-wave simulator, Ansys-HFSS, all of the antenna designs examined are determined to be lacking to some degree.

  • Transmitting Antennas for Hf Broadcasting
    TRANSMITTING ANTENNAS FOR HF BROADCASTING Broadcasting Services Division [email protected] 1. INTRODUCTION Transmitting antenna remains one of the key components of any broadcasting system. For HF broadcasting, where the signal is propagated via ionospheric transmission over long distances, the selection and design of a suitable transmitting antenna system is therefore extremely important. Careful design of transmitting antenna systems results in adequate coverage of the intended target areas and at the same time reduces radiation outside the target areas. This minimises the potential for interference to between HF services and consequently improves the spectrum productivity of the already crowded HF broadcasting bands. As part of the new planning procedures for the HF bands (Article S12 of the Radio Regulations), a compatibility analysis of all HF requirements submitted is to be made available for Administrations, broadcasters, frequency manager organisations to use in their coordination of the broadcasting requirements. This analysis requires accurate descriptions of broadcasting systems in use, particularly of the transmitting antenna systems. Furthermore, the analysis also requires a common set of antenna code in order to facilitates the identification and notification of transmitting antenna systems. This paper discusses a number of common used HF transmitting antenna systems and proposes a corresponding system of reference antenna codes. The latter was developed in close consultation with regional coordination groups ABU-HFC, ABSU and

  • Antenna Measuring Notes
    Antenna Measuring Notes: Kent Britain WA5VJB (Written for Scatterpoint issue 1-2000 updated Sept 2006) Since 1987 I have set up my portable antenna range at 26 Conferences measuring well over 1500 antennas, mainly in the 0.9 to 24 GHz range. G4DDK has asked me to list some of my observations. The Feed is not at the focus of the dish: First off, I have NEVER been able to calculate the focal point of my dish, mount the feed, and have the antenna optimized. NEVER! It always seems I have to move the feed in towards the dish a bit to tweak things up. But out of the antenna range things are far worse. About half of the dishes have the feed off by as much as 50% in distance! A chap comes up with a 2 ft. dish and about a 0.35 f/d. The feed is sticking out 3 ft from dish! "But that's where I calculated the focus to be!" is always the answer. I haven't found out what in the D²/16c equation throws them, but we see it all the time. Another problem is the rounded edge on most dishes. They measure the physical diameter of the dish, not the diameter of the actual parabolic surface. That outer cm or so of many dishes is not usable and should not be used in the F/d calculations. And I won’t even start on the complications of calculating the actual phase center of the feed. I have always been able to pick up a dB or two tweaking the focus and 6 dB or so has been the typical improvement at the conferences when the feed is movable and we can optimize its position.

A novel wideband circularly polarized antenna array using sequential rotation feeding network is presented in this paper. The proposed antenna array has a relative bandwidth of 38.7% at frequencies from 5.05 GHz to 7.45 GHz with a highest gain of 12 dBi at 6 GHz. A corresponding left-handed metamaterial is designed in order to increase antenna gain without significantly affecting its polarization characteristics. The wideband circularly polarized antenna with 2.4 GHz of bandwidth is a promising solution for wireless communication system such as tracking or wireless energy harvesting from Wi-Fi signal based on IEEE 802.11ac standard or future 5G cellular.
