Summary:
In this paper, a vertically circular patch antenna excited by probe with cross strip above vertically rectangular reflector is proposed. The proposed antenna is used for Base station of WLAN system. The antenna is analyzed by CST (Microwave studio) program. A prototype antenna operating at 2.45 GHz. with an impedance bandwidth (2:1 VSWR) of 37.62 % from measured result (about 2.105-3.000 GHz). The proposed antenna is unidirectional radiation pattern with front-to-back ratio (F/B) of greater than 20 dB in H-plane and E-plane radiation patterns. Maximum gain is about 9 dBi from measured result. The half-power beamwidth (3dB) is about 58.8 degree in E-plane and 65.0 degree in H-plane. The cross polarization greater than 20 dB has been obtained.
