“…The excellent performances of the antenna are mainly due to the shorted annular stacked patch structure and four ports proximity-coupled probe-fed feeding mechanisms. Axial ratio and gain characteristics at low elevation are better than the other structures designed for GPS or GNSS application [8][9][10][11][12][13][14], which are compared in Table 2. The simulated and measured RHCP gain of the antenna at different frequencies are presented in Figure 12, and it is observed that the stable gain bandwidth can be obtained for gain > 2.5 dBi in the GNSS bands.…”

“…There are mainly three methods to achieve broadband performance of microstrip antennas, they are using two or more radiating structures which work at different but contiguous resonant frequencies [4,5], using coupling feeding scheme [6] and adding external matching circuits [7]. Several multi-band or wideband lowprofile antennas have been designed in the literature [8][9][10][11][12] for GPS or GNSS application. However, few of them can obtain broad beam width and good axial ratio at low elevation, which are useful to suppressing multipath interferences.…”

Abstract-A new design of a compact circularly polarized shorted annular stacked patch antenna has been introduced for Global Navigation Satellite System (GNSS) in this paper. The wideband characteristic is achieved by employing L-probe coupled feeding structure. The antenna is fed by four-output-ports strip line feeding network composed of three normal Wilkinson power dividers. As a result, the designed antenna has an effective bandwidth of 94.3% from 0.7 GHz to 1.95 GHz for VSWR < 2, and 57.1% 3-dB axial ratio bandwidth from 1.0 GHz to 1.8 GHz, respectively. The designed antenna has a compact size of 100 mm × 100 mm × 13 mm. The final antenna provides very good circularly polarized radiation for GNSS including GPS, GLONASS, Galileo and Compass.

Novel design of stacked circularly polarized strip lines fed patch antenna has been proposed for global navigation satellite system in this article. The antenna has been designed to operate for the satellite navigation frequencies including GPS, global navigation satellite system, Galileo and Compass (1100—1600 MHz). Three normal Wilkinson power dividers are connected together acting as the feeding networks. As a result, the antenna has a 57.6% 10‐dB return loss bandwidth from 1.05 to 1.9 GHz and 42.9% 3‐dB axial ratio bandwidth from 1.1 to 1.7 GHz, respectively. Crossed slots are cut on the radiating patch to increase the antenna gain. The designed antenna in this article can acquire broad beam width and good axial ratio at low elevations. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2062–2066, 2013

“…For the small footprint available, it is not possible to fit three planar crossed dipoles. To overcome this problem, the dipole elements can be raised vertically and configured in the aperture to obtain good performance [9]. But again, the height is increased.…”

An adaptive antenna for handheld GPS receivers is presented. The antenna has a small aperture, small volume, and is lightweight. The antenna uses four spiral elements to provide broadband satellite coverage and can also be used in conjunction with a space-time adaptive processor (STAP) for interference suppression. The antenna with integrated feed is easy to fabricate as well. The performance of a simulated and experimental antenna is compared and found to be in agreement. Finally, the nulling performance of the antenna is examined for a few simple interference scenarios. ANTENNA DESIGNAn adaptive antenna for a handheld GPS receiver needs to possess a number of electrical and physical characteristics. The first electrical characteristic is three-dimensional interference suppression. To provide this, the antenna needs to have at least three elements. The second electrical characteristic is satellite signal reception. For this, the antenna needs to have a broad right-hand NAVIGATION:
