Abstract
Design of a broadband, dual-polarized suspended patch antenna covering 2G/3G/Wi-Fi/4G bands (1710-2690 MHz) is presented. The prototype consists of two suspended plates and a feedline layer. Excitation of ±45 slant dual polarization is realized by a novel crossed elliptic-H slot. The prototype exhibits 48.7% impedance bandwidth (|S11|, |S22| < −15 dB) in 1660-2730 MHz. Port isolation (|S21|) is obtained as > 28 dB. In desired operating band, stable and symmetric radiation patterns with half-power beamwidths of 55-75 and 65-74 in E and H planes are measured, respectively. Gain variation lies within 8.3±0.8 dBi. Proposed antenna is low profile, has high port isolation and high front to back ratio without needing any secondary reflector ground plane. With these qualifications and performance specifications, it outperforms many of the similar works in the literature. Design considerations, simulations and measurement results of proposed antenna are presented and discussed.
