Compact Dual-Band Broadband Microstrip Antenna for WLAN Applications

This paper presents a compact planar monopole antenna with dual-band operation suitable for wireless local area network (WLAN) application. The antenna occupies an overall area of 18 × 12 mm2. The antenna combines two folded strips is fed by a coplanar waveguide (CPW) transmission line, which radiates at 2.4 and 5.2 GHz. Prototypes of the obtained optimized design have been simulated using HFSS. The simulated results show good dual-band operation with -10 dB impedance bandwidths of 50 MHz and 2400 MHz at bands of 2.4 and 5.2 GHz, respectively, which covers the 2.4/5.2/5.8 GHz WLAN operating bands
