This study presents a novel technique for minimizing RF leakage in metallic hollow waveguides fabricated using the multilayer split-block method. By integrating a pin/hole wall into the split-block multilayers, a substantial reduction of RF leakage can be achieved while reducing the circuit size and mitigating the performance variations. To validate the proposed approach, a slot antenna fed by single ridge waveguide has been prototyped and experimentally validated. The simulated and measured results demonstrate that the slot antenna is well matched (|S11|  –10 dB) within the frequency range 29 GHz to 34 GHz, whereas its gain is about 8 dBi.
