Abstract :
A new design of a V-band hyper-non-radiative dielectric (HNRD) guide directional coupler using a multi-hole structure is described and measured results are given. The coupling structure using multi-hole between the two HNRD guides is employed to obtain wideband coupling. Measured results for the fabricated 3 and 10 dB coupler showed that return loss is greater than 16 dB, isolation is better than 26 dB, and the average coupler loss is 1.1 dB, over a percentage bandwidth of 10% at 60 GHz.
