A wideband, low cross-polarization, high-gain, and wide-angle scanning antenna array is presented in this paper. The antenna array contains 8 subarrays in the horizontal dimension, and each subarray contains 4 unit cells. A two-side printed dipole with an amendatory equivalent circuit model is adopted, and the metal vias are introduced in the element design to ameliorate the cross-polarization level. A radome, acting as the wide-angle impedance matching layer, is introduced to achieve wide-angle scanning. A prototype of a 4 × 8 array is fabricated and measured. The results show that the operating bandwidth of aperture efficiency (BWAE) above 60% is about 26.7% from 2.6 GHz to 3.4 GHz. The measured scanning loss in the H-plane is 2.7 dB when scanning up to 60° with active voltage standing wave ratio (VSWR) <3, and the gain can achieve 21 dB at 3 GHz with a cross-polarization level below −30 dB at all angles.

An eight shaped annular ring slot antenna array is presented. Feed is designed with T shaped Power divider and quarterwave transformer is used. Antenna element is comprised of two linked annular slots to achieve high band width. Analysis is carried out with HFSS simulation software. Array is configured with corporate feed structure. It has been observed tha gain is increased to 4dB to 5dB and return loss band width increased from 600 MHz to 1.2 GHz around 55%, Cross polarization level also significantly decreased,
