The model and simulation of a novel substrate integrated waveguide (SIW) sum-difference comparator based on 3 dB-coupler with 90deg phase delay is proposed. Equivalent model method is used to determine initial geometric sizes and numerical software simulation is used to make optimization and obtain electrical characteristic variations and electromagnetic… (More)
