Abstract

A quarter-wavelength diversity patch configuration for the 2.4-GHz ISM band PC card application is reported. The structure is based on partly interdigitation of two quarter wavelength separated patches through a set of fingers for achieving the required space diversity on single side printed substrate with an easy matching on 50 Ω, high cross-polarization and within a given maximum space of 30 mm×50 mm. Measured antenna patterns for the developed structure are the same as for a classical patch and the bandwidth for a VSWR less than two is 2% with a maximum gain of 1.5 dB. This antenna has been incorporated in a high-speed wireless LAN PC card system
