Enhanced dual polarization directional coupler for dual polarization beam forming networks
2000 IEEE MTT-S International Microwave Symposium Digest (Cat. No.00CH37017), 2002Directional couplers and fixed phase shifters are the key components for the realization of beam forming networks. Usually a beam forming network feeds the antenna with two linear and orthogonal polarizations. Dual polarization components can be used to reduce complexity and size of a beam forming network.

Cross-polarization in dual polarization switching antennas
International Journal of RF and Microwave Computer-Aided Engineering, 2007This paper presents the effect of the interaction between the switch and the antenna parameters on the cross-polarization of a dual polarization switching antenna. It is shown that the isolated antenna cross-polarization combines with the isolation of the switch giving place to a degradation of the polarization purity of the combined dual polarization ...

Polarization Error Compensation in Dual-Polarization IFOGs
2017In this chapter, two kinds of dual-polarization IFOGs are designed and experimentally tested, and the phenomenon of polarization nonreciprocity (PN) error compensation between two polarizations is observed. The experimental structures ensure that two polarizations are independent for rotation sensing.
