Abstract

A tunable antenna with continuously sweeping linear polarization (LP) is proposed in this paper. This tunable antenna consists of a variable power divider (VPD) based on Composite Right/Left-Handed (CRLH) transmission line and a patch antenna. The VPD is a combination of a Wilkinson power divider, a 90 degree bridge and two CRLH tunable phase shifters. The CRLH phase shifters are the core tunable components making the VPD to be tunable. The measurements show the ratio of the VPD can reach -20dB to 20dB and the linear polarization of the tunable antenna can continuously sweep for all directions.
