Abstract
In this paper, a circular vertical patch antenna excited by probe with cross-strip above cylindrical reflector is proposed. The proposed antenna is used at base station for point-to-point communication in wireless local area network systems (WLAN). The antenna is analyzed by CST (Microwave Studio) program. The measured results of the prototype antenna operating at 2.45 GH z yields an impedance bandwidth (2:1 VSWR) of 32.60% (2.23-3.10 GHz). The antenna has unidirectional radiation pattern with front-to-back ratio (F/B) of greater than 26 dB in E-plane and H-plane. Maximum gain is about 9.7 dBi from measurement. The half-power beamwidth is 56 degree in E-plane and 58 degree in H-plane. The cross polarization of greater than 30 dB in both planes has been obtained.
