Abstract

This paper presents a design of compact size dual-band antenna for Wi-Max, C and X-band applications. The modified symmetrical step sized slit is etched on the coplanar waveguide (CPW) ground plane. The radiating patch and CPW ground plane are designed on a 1.6 mm thick FR4 dielectric constant Ɛ_r=4.4 and tan =0.002 with the compact size of 10×10 mm². The antenna is designed to operate in dual band. The Wi-Max band (5.2 GHz) is obtained by etching a split ring on the rectangular microstrip patch. The operating bandwidth is obtained from 5.22 GHz-5.38 GHz (3.72 %) and 7.28-8.48 GHz (15.22 %). It has maximum gain of 2.1 dBi at 7.9 GHz and radiation efficiency above 95%. The Co and cross-polarization level is -45 dB and -32 dB in E and H-plane at 5.3 GHz, respectively. The Co and Cross-polarization levels are -40 dB and -28 dB at 7.9 GHz.
