✦ Synopsis

The impedance bandwidth and cross-polarization characteristics of quarter-wa¨e shorted patch antennas are in¨estigated experimentally. It is found that, for a square quarter-wa¨e patch on foam substrate of thickness 5.8% of wa¨elength, the bandwidth is 18.54%, which is more than three times that of the half-wa¨e patch. The cross polarization in the H-plane is ¨ery large at oblique angles, e¨en if a think substrate is used.

## Abstract A broadband high‐gain single‐feed cross‐aperture coupled patch antenna is presented in this paper. The measured results confirm that the antenna is capable of a 14.4% impedance bandwidth (VSWR ≤ 2), 3% of 3‐dB axial‐ratio bandwidth, and 17.4% of gain (>8 dBic) bandwidth with a mean gain

## Abstract This article presents a novel design of complementary‐symmetry aperture‐coupled microstrip antenna for wideband, adequate gain, and low cross‐polarization. An experimental bandwidth of 129.51% with gain of 5.17 dB is achieved. The antenna operates from 3.85 to 18 GHz, which covers C, X,
