Abstract
A coplanar waveguide (CPW) square-ring slot antenna for use in wireless communication systems is miniaturized and reconfigurable by the integration of ferroelectric (FE) BST (barium strontium titanate) thin film varactors therein. The slot antenna device includes a sapphire substrate, top and bottom metal layers, and a thin ferroelectric BST film layer, where the FE BST varactors are integrated at the back edge of the antenna on the top metal layer.
