Abstract

This article presents the design and performance of a wideband folded shorted patch antenna. The proposed antenna consists of a folded trapezoidal patch that is shorted to the ground plane and is fed by a coaxial probe. By offsetting the probe feeding position from the midline of the patch, wide impedance bandwidth of 56.1% (1.59–2.83 GHz) is obtained for SWR < 2, which is nearly two times that of the antenna without offsetting the probe. The patch of this antenna is 0.071λ~0~ in height and 0.35λ~0~ in length, where λ~0~ is the free space wavelength at the center frequency of its operating bandwidth. Therefore, this antenna is suitable for the multiband indoor wireless communication systems nowadays. © 2008 Wiley Periodicals, Inc.

## Abstract A wideband microstrip patch antenna with tilted L‐probe is proposed and studied. Given a tilted L‐shaped probe and substrate height of about 16.8% of the wavelength, a bandwidth of 37.1% is obtained in the design, and the in‐band __S__~11~ parameter is improved.

The L-shaped probe is shown to be an excellent feed for the thick circular patch antenna. The substrate used is a foam layer of thickness about 10% of the operating wa¨elength. An impedance bandwidth of 24% and an a¨erage gain of 7.5 dBi are achie¨ed.

## Abstract A two‐element hexagonal‐shape stacked‐patch antenna array fed by an L‐shaped probe is designed and measured. Experimental results show that the array achieves an impedance bandwidth of 34% (SWR < 1.5)/44% (SWR < 2) and a gain of 11.5 dBi. The far‐field radiation pattern is stable across

## Abstract In this paper, we present a single‐feed shorted patch antenna with low cross‐polarized radiated fields. The printed antenna uses two shorted parasitic elements symmetrically located around the driven shorted patch. These elements electromagnetically balance the radiator. We have experim
