Abstract:
A compact band-notched ultra-wideband (UWB) spatial diversity antenna is presented in this paper. The antenna is fabricated on an FR4 substrate and consists of two tapered microstrip feeding lines and two radiating elements. The wireless local area network (WLAN) for IEEE 802.11a operating in 5.15-5.825 GHz and-notched function is achieved by introducing two slits in the radiators as λ/4 resonators. The simulated and measured results show that the presented antenna has a broadband impedance bandwidth which covers UWB band and also has a band-notched characteristic. Additionally, the antenna has a good transmission coefficient better than -15 dB across the UWB. The radiation patterns, peak gain, and envelope correlation coefficient are measured and discussed.
