Abstract

This paper is focused on the study of the tunability of planar composite right/left handed (CRLH) transmission lines based on the combination of open split ring resonators (OSRRs) and open complementary split ring resonators (OCSRRs), and its application to microwave devices. The tunability is achieved by means of Barium-Stronium-Titanate (BST) thick films, which change the electrical properties of the structures through the application of an static electric field. Some potential applications such as phase shifters or tunable band pass filters are presented, where a frequency tunability of 36.6% is obtained.
