Incorporating phased array technique to scan the main beam of a Fabry-Perot cavity (FPC) antenna produces sidelobes proportional to the scan angle. An alternative dielectric-ferrite superstrate-based scan mechanism with controlled sidelobe level is presented in this letter. A beam scan of 24 <sup>&#x00B0;</sup> is demonstrated by axially magnetizing the(More)
Design of power dividers are critical for large array antennas, where radiation patterns are controlled by adjusting the magnitudes and phases of the patch excitation signals [1]. In a non-uniform array, side-lobe levels are often reduced by tapering the excitation magnitudes of individual patch to strength the radiation from the central patches. This(More)
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(More)
