Novel compact uniplanar printed CPW-fed M-antenna

A compact printed CPW-fed novel M-antenna is presented. The proposed antenna consists of an M-shaped radiator with CPW-feed. A parametric study on several geometrical parameters on its performance is provided to optimize the antenna. Hence, with the compact antenna size, two antennas for DCS1800 and 4G systems are achieved. Details of the design considerations are presented, and results of the fabricated prototype are discussed.
