Abstract
This paper describes a novel configuration of a CPW-fed printed monopole antenna that depicts dual-band operations of WLAN and X-bands. The proposed antenna consists of a simple rectangular-shaped patch as the main radiator, the modified mirrored L-shaped conductor back plane element, and the partial rectangular CPW-ground surface. Dual-band performances can be obtained by embedding and adjusting dimensions of strips on mirrored L-Shaped conductor back plane element. The impedance bandwidth with \(\hbox {s}_{11} < -10\) dB is about 2.2 GHz (5.05–7.25 GHz) or 36 % for 5 GHz band and 5.2 GHz (7.6–12.8 GHz) or 51 % for X-band. The measured peak gains are about 1.8 dBi at WLAN-band and 4.3 dBi at X-band. The Experimental results indicate that the fabricated antenna with proper dimensions, good radiation characteristics, and reasonable measured gains can be a good candidate for various applications of the future multi-band wireless communication systems and mobile device.
