PAA (Phased array antenna) has the capability to scan from one beam direction to another beam direction within few microseconds. The BFN (beam forming network) is the part of phased array antenna. The BFN is composed of power dividers and phase shifters. The phase shifters are controlled by BSC (beam steering computer). Usually, one beam pattern is generated by one BFN. Dual identical phased array antennas with symmetry beam patterns is simulated and designed by the same BFN. These two patterns are symmetry in azimuth plane. The performance of new type of phase shifter and its applications will be detailed discussed in this paper.
