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 level of 9.3 dBic. The techniques for obtaining high gain and broad impedance bandwidth as well as the effects on aperture size are discussed. © 2003 Wiley Periodicals, Inc.

## 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,

In this paper, the tilt of a feedline with regard to a slot is taken into account to impro¨e the ca¨ity model, and also to see the effect of this angle on the input impedance. In fact, the angle is introduced in the ¨oltage discontinuity of the slot on the feeding line. The computed results are comp
