Abstract	:	A simple steerable array antenna is designed and developed using a movable dielectricphase shifter. The change of the effective dielectric constant at different dielectric slabpositions on a coplanar waveguide is used as the phase shifter. The impedance matchingand desired phase shift conditions are satisfied at two slab heights, and the reflection isdesigned to be minimized at these slab positions. A low-loss dielectric material is usedas the dielectric slab and is placed close to a coplanar transmission line with an airgap.Numerical simulations using Ansoft HFSS and Designer are conducted.
