Abstract
A phase shifter, such as for use in phased antenna arrays, comprising thin film BST capacitors periodically loading a transmission line. The BST thin films can be deposited using RF sputtering on a variety of substrates, and the capacitors can be of a parallel plate configuration or of an interdigitated configuration. An aspect of the invention additionally provides for the use of periodically distributed lumped-element inductors comprising the transmission line. A further aspect provides for programmatic determination of circuit design and configuration parameters based on the input of desired characteristics and materials for the phase shifter.
