Abstract :
The authors design two types of HNRD guide to rectangular E-plane waveguide transitions with a fractional bandwidth of 10 or more percent for -20 dB return loss and a directional coupler of HNRD-E-plane waveguide integrated structure on the basis of the transverse resonance technique (TRT). The theoretical results are in good agreement with results calculated by an EM-simulator (Ansoft HFSS).
