Abstract :
Important parameters of waveguide diplexer components as lowpass filter and combiner, have been improved. Concave shaping of vertical walls of a corrugated filter decreases reflection coefficients by 10 dB in the 14.5-15.35 GHz band. Placement of inserts at the antenna port of a combiner increases bandwidth by more than 50%.
