Abstract

A novel compact square slot antenna design with coplanar waveguide (CPW)-fed for dual-band operation is presented. The proposed antenna is simply composed of a square slot resonator and a monopole radiator. By employing the special square slot structure, the antenna can achieve a new resonance while maintaining a small size. Based on this concept, a prototype of dual-band antenna is designed, fabricated and tested. The experimental results show the antenna has the impedance bandwidths of 400MHz (2.33{2.73GHz) and 1020MHz (3.27{4.29GHz), covering both WiMAX in the 2.5/3.5GHz bands and WLAN in the 2.4GHz band.
