Abstract
In this paper an electronically steerable antenna using a tunable ferroelectric material is proposed. Ferroelectric materials such as barium strontium titanate have been used as a traveling waveguide with a ground plane on one side and a metallic periodic grating on the opposite side. The dielectric properties of the ferroelectric material are changed by a bias voltage applied to the waveguide which in turn controls the leaky wave direction of the antenna. Results from a simple experiment are presented which show good agreement with theoretical predictions.Keywords
