Abstract

Design and fabrication of a traveling-wave printed planar composite right/left-handed (CRLH) antenna are presented in this paper. The proposed traveling-wave antenna constructed of four unit cells with b-shaped geometries, which each occupy 2.49 mm length, 6.32 mm width, and 0.8 mm height. In this paper, with designing the optimized b-shaped printed planar structure by the standard manufacturing techniques on the printed circuit boards, which perform the roles of the series left-handed (LH) capacitances (CL), the antenna size, bandwidth, and radiation specifications may be improved to the desirable range. Also, to obtaining the desired results the spiral inductors have been used, which play the roles of the shunt LH inductances (LL). The fabricated antenna with the proposed structure can be covered more from 2 GHz measured impedance bandwidth with minimum of the measured gain and radiation efficiency equal to 6.1 dBi and 52.3%, respectively, which happen at 9 GHz. According to the provided results, the proposed compact ultra-wideband traveling-wave antenna is a potential candidate to use in the embedded electronic systems and portable wireless communication devices.
