Abstract

A surface wave antenna having an antenna gain of 6.80 dBi and an FB ratio of 15.44 dBi at 8.4 GHz is presented. This antenna is vertically polarized and achieved unidirectional beam pattern in horizontal plane. It is composed of a loop element and an enclosing element which has an open end to obtain unidirectional beam pattern. Furthermore, a monopole array antenna model is used for verification of the antenna mechanism. The cause of the cross polarization is ascertained using the array model, and the method to reduce the cross polarization is also presented.
