Novel Design of Broadband Strip Lines Fed Patch Antenna for GNSS Application

Abstract

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

A compact omni‐directional circularly polarized antenna for WLAN applications

“…The basic principle to design an omni-directional CP antenna is to obtain two orthogonal fields with the equal amplitude and 908 difference in phase. Various omni-directional CP antennas have been proposed over the past few years [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In [1], an omni-directional CP antenna based on the zeroth-order resonance (ZOR) mode of epsilon negative transmission line is proposed and the horizontal polarization is obtained by the curved branches while ZOR transmission line generates the phase difference of 908.…”
