A Multi-Band Monopole Antenna with a Parasitic M-Strip for PCS and WLAN Applications

Abstract

A multi-band monopole antenna is proposed in this paper. The antenna consists of a parasitic M-strip and an elliptical slot etched in the ground. With the help of the parasitic M-strip and the slot, the Y-shaped monopole antenna can easily obtain multi-band characteristics. The proposed antenna has been constructed and tested. The simulation is identical to the theoretical result. The simulated and tested results show that the proposed antenna impedance bandwidths make it easily cover the required bandwidths for PCS band, and WLAN band applications. The results also show the better comprehensiveness at the H plane.
