A printed multi-frequency monopole antenna for WLAN/Wi-MAX systems

In this paper a novel compact triple frequency monopole antenna with elliptical slot, is presented for WLAN and Wi-MAX applications. This antenna composed microstrip-fed circular disc with elliptical slot included a strip, and a ground plane with rectangular slot. The designed antenna operates at 2.63, 3.48 and 5.8 GHz band having peak gain of 2.7 dBi at 2.63 GHz, 2.45 dBi at 3.48 GHz and 2.96 dBi at 5.8 GHz frequency. The presented antenna has compact size of 18 × 25 × 1.6 mm3 and simple structure which covers 2.37-2.90, 3.40-3.69 and 4.96-6.4IGHz frequencies for WLAN and Wi-MAX systems.
