Abstract

Spatial segregation by enhancing the distance and time isolation by reducing the duty cycle are ways to achieve isolation between the receive and transmission antennas in RF front-end of wireless systems. More and more systems tend to share the same antenna feed network, which needs a transmission and receive isolation duplexer to ensure the sharing of one antenna and sufficient T/R isolation. In this paper, we conclude the characteristics of different sorts of traditional duplexer, declare the development and application of the quasi-optical T/R polarization isolation duplexers which worked with same frequency during high frequency band, and consider the relationship between the electromagnetic propagation principle and metal fences of different shapes about those duplexer. In addition, we discussed the application perspective of designing the T/R polarization isolation duplexers based on meta-materials in the future.
