Abstract

Abstract

As the application of SATCOM On-The-Move (SOTM) is restricted by the height of antenna, the planar antenna with multiple subarrays is adopted to reduce the height of antenna. However, the excursion of beam pointing versus frequency is deteriorated because of its dispersed aperture. In order to reduce the excursion of beam pointing, the feeder system using fixed delay line and phase shifter is applied in this paper, and the switching-beam technique based on multi-set fixed delay lines is proposed. The proposed method divides the antenna scanning range into several small ones, and uses different fixed delay lines in each range. Simulation results show that the method can reduce the excursion of beam pointing effectively, and the requirement of beam pointing accuracy for SOTM can be satisfied.
