Abstract

A printed meandering strip (PMS) is proposed for feeding a patch antenna. It is demonstrated that the impedance matching of the antenna can be further improved by using a higher order PMS. A patch antenna fed by a first order meandering strip has an impedance bandwidth of 22% [standing wave ratio (SWR) < 1.5], cross polarization level of less than โˆ’25 dB and a gain of 9 dBi. The measured impedance bandwidths of a second order PMS and a third order PMS are 12% (SWR < 1.2) and 8% (SWR < 1.1), respectively. They have an average gain of about 9 dBi and cross polarization levels are low in level. All measurements have been confirmed by simulation. ยฉ 2007 Wiley Periodicals, Inc.

## Abstract In this paper, the characteristics of a bent meanderโ€line probe fed patch antenna are investigated. The airโ€filled patches are designed at a height of about 9% of the wavelength and the bent meanderโ€line probe fed antenna is able to achieve an impedance bandwidth of about 31% for a VSWR

## Abstract A linearly polarized electrically long rectangular patch antenna fed by a meandering probe is presented. By increasing the width of a patch antenna to 1.05ฮป~0~, the gain of the antenna can be increased. The antenna has an impedance bandwidth of 26% (SWR < 1.5), a gain of 11.2 dBi, and a

## Abstract Simple foldedโ€patch antennas fed by an Lโ€shape probe are designed and studied experimentally. This simple antenna structure with thick air substrate attains a projectionโ€length reduction of about 30% with reference to the conventional halfโ€wave patch antenna. This antenna attains an imp
