Abstract :
The beam scanning properties of a 2-element patch array fed by a microstrip feed situated on a ferrite substrate are presented. Biasing the ferrite changes the phase length of the microstrip line, scanning the beam by up to 40°. The resulting scan loss is ~2 dB, mainly due to the ferrite becoming lossy as it approaches absorption resonance
