Abstract
In this paper, the sequentially rotated array(SRA) antenna with 256 elements applicable for satellite broadcasting reception was designed by arraying this triple(4+8+4 element) SRA antenna as a sub-array antenna. The structure of a triple SRA antenna is a combination of three coaxial shells composed with 4 elements of inner shell and 8 elements of middle shell and 4 elements of outer shell. In accordance with the optimum design rules for realizing a high gain antenna, the sequential array factors(M, P) of inner shell and outer shell have been chosen M=4 and P=1 and that of middle shell has been chosen M=8 and P=1. The results of the simulation and the measurement for the proposed triple(4+8+4 element) SRA antenna and the SRA antenna with 256 elements show good characteristics on the integration, bandwidth of the axial ratio and the cross-polarization, the gain respectively.
