【摘要】 本文提出了一种基于间隙波导的全双工天线馈电网络。本文利用4个双频耦合器设计了一种结构简单紧凑的全双工无源馈电网络,并结合三层基片间隙波导使系统更紧凑,进一步提高了收发隔离度。仿真结果表明,采用该方案设计的全双工系统能够在8.05GHz和11.7GHz分别获得-53.3 dB和-52.8 dB的收发隔离度,同时还具有结构简单和尺寸紧凑的优点,为高速无线通信提供了有效的解决方案。更多还原

【Abstract】 This paper presents a full duplex antenna feed network based on gap waveguide.In this paper,four dual frequency couplers are used to design a simple and compact full duplex passive cancellation feed network.Combined with three-layer substrate gap waveguide,the system is more compact and the transceiver isolation is further improved.The simulation results show that the full duplex system designed with this scheme can achieve-53.3 dB and-52.8 dB transceiver isolation at 8.05 GHz and 11.7 GHz,respectively.At the same time,it also has the advantages of simple structure and compact size,which provides an effective solution for high-speed wireless communication.更多还原
