Author Affiliations +
Phase shifters are performing very important role in the performance of electronically steerable phased arrays. In this paper we have demonstrated the performance of microstrip line and planar phase shifters on (Ba-Sr)TiO3 (BST) substrate. It requires very low drive power and has low production cost. Because of the large tunability of the dielectric constant of the BST materials with the dc bias voltage, these materials are suitable for the electronically steerable antenna applications. The performance of the filter phase shifter and microstrip line phase shifter are evaluated and it is observed that the filter phase shifter shows better performance compared to the microstrip line phase shifter.
