Symmetry antenna patterns of PAAs by sharing the same phase shifters of BFN

New type of phase shifter for BFN of identical PAAs is simulated and developed. The relationship of two phase outputs of phase shifter has been discussed. By using this property, BFN with this type of phase shifters can be shared by two identical PAAs. Two symmetry opposite beam patterns can be generated by these two PAAs. Hardware implementation of phase shifter is designed as shown in Fig.4. The computer modeling of BFN is shown in Fig.5. The hardware of BFN is shown in Fig.6. The computer model of antenna element and prototype is shown in Fig.7. Test results will be detail discussed during the presentation.
