Abstract :
This paper presents a six-port coupler with high directivity for VSWR measurement. By using capacitive compensation, dramatic achievement of over 35dB directivity with microstrip configuration at the central frequency is achieved. The design procedure of the coupler is provided. All analytical results are categorically verified by experiment.
