Abstract
A ferroelectric phase shifting antenna array consists of a plurality of lrally spaced antenna patches which have respective ferroelectric components abutting an edge of each patch at a near central location on the edge to provide impedance matching. DC control power lines are connected to the center voltage null position of the resonant mode of the antenna patch. An Rf source is connected to the other ends of the ferroelectric components through quarter wave coupled lines which provides simultaneous impedance matching and DC isolation.
