Abstract

A wideband composite right/left handed transmission line (CRLH-TL) antenna with cavity-backed substrate integrated waveguide (SIW) is proposed in this letter. This proposed antenna consists of a 2×2 array of mushroom unit cells, feeding line and cavity-backed SIW. By introducing SIW structure both impedance and gain of the antenna are improved. The proposed antenna has average gain of 7 dBi (peak measured gain 9.5 dBi), wide -10 dB impedance matching bandwidth of 55% from 5.2 GHz to 8.3 GHz, small size of 40 mm×50×4 mm, high integration ability, and reduced back radiation.
