Abstract
A unique single probe fed rectangular patch antenna, working at 10 GHz, with a split ring resonator (SRR) embedded ferrite superstrate has been presented in this paper. DC biasing of the ferrite superstrate results in a change in the main beam of the antenna structure. Proper biasing of the appropriate ferrite rod leads to a maximum beam scan of ±17°. A comparison with the beam scan characteristics of the no SRR case show a significant decrease (87.5%) in the antenna thickness and similar beam scans at comparatively much lower DC biasing values. The presented antenna shows a slightly less directivity because of the signal losses encountered due to the biased ferrite; this can be improved by using modified superstrate layers.
