High Gain Wideband Non-uniform Ku-band Array Antenna
In this work a cavity backed metallic-slot antenna constructed from design of $8\times 8$ subarrays operating in the Ku-band is introduced. The proposed array is designed to have low-sidelobe levels (SLL) in both E-& H-planes using quasi-Taylor amplitude tapering. The wide operating bandwidth in this Ku-band array comes from using parallel feeding network with one to 64 parallel directions utilizing the corporate feed in order to stimulate the aperture coupling slots in the upper layer above the feeding network layer. The proposed array antenna is designed to have 12.6-14.3% bandwidth, and a peak gain of 32.3 dB within the bandwidth. Also, the Ku-band array antenna has a good cross-polarization discrimination (XPD) better than −41 dB.
