Abstract

This paper presents novel hybrid antenna (HA) design based on shaped reflector for mobile satellite communications. HA is composed of a shaped reflector and the feeder having a 1x8 linear phased array, and reflector shaping method is applied for the performance optimization with minimum aperture size. And, in the feeder design, HA has another merit to minimize the manufacturing cost by optimizing the number of element. Proposed HA is designed at Ka-band and can electrically control a beam pattern within ±3° in the basic angle of+45° in elevation. This antenna is designed to meet the international regulations for very small aperture terminals (VSAT) including ITU-R S.465-5 for beam pattern including side-lobe level.
