Design of meandering probe fed microstrip patch antenna for wireless communication system

A wideband, low cross-polarization patch antenna fed by meandering probe is presented in this paper. The patch antenna consists of inverted patch structure with air-filled dielectric, slotted patch and meandering probe. The composite effect of integrating these techniques and by introducing the proposed patch, offer a low profile, broadband, high gain, and low cross-polarization level. The results for the VSWR and co-and cross-polarization patterns are presented. The antenna operating the band of 1.84-2.29 GHz shows an impedance bandwidth (2:1 VSWR) of 22% and a gain of 10.6 dBi with a gain variation of 1.02 dBi. Good radiation characteristics, including cross-polarization level in xz- and yz-plane are -50 dB and -23 dB respectively, have been obtained.
