Abstract

A simple steerable array antenna is designed using a movable dielectric phase shifter. The change of the effective dielectric constant at different dielectric slab positions on a coplanar waveguide is used as the phase shifter. The impedance matching and desired phase shift conditions are satisfied at two slab heights, and reflection is designed to be minimized at all slab positions. A four‐element steerable array antenna at 5.8 GHz is fabricated and measured for testing purposes. © 2006 Wiley Periodicals, Inc.
