Abstract
A mechanically steerable antenna was designed using an adjustable phase shifter which employs a dielectric slab placed close to a coplanar TL. Numerical simulations using Ansoft HFSS were conducted at 6 GHz, and a 4-element antenna was tested. A similar design can be used for a digital phase shifter with a matched impedance at the designed frequency.
