A modified dual-band microstrip patch antenna with U-slot
一种用于WLAN的U形槽加载的双频贴片微带天线

Discusses a novel microstrip antenna with a U-slot on the patch.This antenna satisfies the requirements of wireless local area network(WLAN)2.4GHz(802.11b) and 5.2GHz(802.11a) applications.The lower and higher resonant frequencies can be easily tuned by adjusting a few antenna parameters.We design this antenna by using computer simulation program Ansoft HFSS,and then some optimizing.The model achieves the required WLAN specifications in terms of beamwidths,gain and cross-polarization level.The antenna bandwidth is 100MHz at 2.4GHz and 300MHz at 5.2GHz,respectively.
