Waveguide Diplexer: Design and Analysis for 5G Communication

Diplexers circuits are recurrently used for mobile communications for 5G and satellite communication and used to separate the high power wide-band of transmission band from the error prone reception frequency range. Various telecommunication services like navigation system or television systems are based on satellite communication. for speed considerations, and in order to manage IoT devices diplexer devices are used. Diplexer is improvement over the microwave filters. This paper presents the analysis of simulated WR-28 waveguide that is used for Ka-Band. The cut off frequency in dominant mode is 30.4 GHz. The design is simulated over a frequency ranging from 20 to 50 GHz.
