Abstract

A novel microstrip antenna with a U-slot on the patch is presented in this paper, which satisfy 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 some optimizing
Followed . 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, respectly.

Key words： WLAN; U-slotted patch; dual-band microstrip antenna
