A Novel Compact Dual Frequency Microstrip Antenna

AbstractA dual frequency, compact single probe-feed rectengular microstrip patch antenna with reduced size has been proposed in this paper. The single layered antenna has been designed to resonate in dual frequency mode. The novel design is achieved by cutting rectangular slits at two sides of the patch. Compared with the conventional rectangular patch antenna, this antenna can achieve reduction in patch size up to 71%. This antenna has been simulated in standard IE3DTM (based on MoM) software and satisfactory return loss for each resonant frequency has been found and this antenna can be used for Wi-MAX and WLAN application
