Abstract

A novel broadband high gain periodic endfire antenna is presented. Broad bandwidth is realized by using a parallel strip line (PSL) feed and bowtie dipole elements while gain enhancement is achieved by loading split-ring resonator (SRR) structure in the endfire direction. The measurements show that SRR-loaded antenna presents gain of about 6.2~9.9 dB in the whole working band (5.1~8.2 GHz), which is about 1.3~4.2 dB more than the unloaded one. This antenna can be used in wireless communication systems for its advantages of broad bandwidth and high gain. [ABSTRACT FROM PUBLISHER]
