Abstract

A kind of hemispherical antenna array based on shape conformal is studied in this paper. In order to solve the polarization problem during beam scanning of the array, the method of phase compensation is adopted. The omni-directional scanning of 0−∘360∘ in azimuth direction and wide-angle scanning of −90to∘ 90∘ in elevation direction are realized. The gain of the array at each scanning angle is about 17 dB. To reduce the occlusion effect of array elements on radiation, the effective elements at different scanning angles are selected for thinned array arrangement. The power loss is reduced and the better scanning performance is achieved by using fewer elements.
