Abstract :
A mechanically steerable antenna was designed and developed using an adjustable microwave phase shifter. The dielectric material ετ = 10 (alumina) was used as the dielectric slab and was placed close to a coplanar TL. Numerical simulations using Ansoft HFSS and Designer were conducted at 20 GHz. For the testing purpose, a 4-element steerable array antenna at 5.8 GHz was fabricated and measured.
