Abstract :
We propose a ferrite-loaded groovy antenna that consists of a ferrite-loaded ground plane with multiple rectangular grooves. The ferrite-loaded groovy antenna is designed, implemented, and tested at 10.08 GHz. The bandwidth of the fabricated antenna is narrow (0.5% for S11≤-10 dB at 10.08 GHz). A beam-scanning range of 21° is achieved when the dc magnetic field increases from 0 to 1100 oe. Measured radiation patterns favorably agree with theoretical results.
