Abstract :
By using twin stepped-patch radiators and a protruded ground, a micro-strip-fed monopole antenna with wide dual-band operation can be obtained. The proposed antenna with an overall size of 32 times 25 mm can excite resonances at the 2.61 and 5.52 GHz bands with impedance bandwidths of 710 MHz (2.32-3.03 GHz) and 1.56 GHz (4.77-6.33 GHz), average antenna gains of 2.9 and 3.5 dBi, respectively, and also monopole-like radiation patterns. These properties make the antenna suitable for 2.4/5.2/5.8 GHz WLAN applications.
