  • Abstract: A new design of an H-polarized leaky-wave antenna (LWA) based on the substrate integrated gap waveguide (SIGW) technology is introduced. The antenna shows good scanning capability from the backward to a near broadside direction (from −36° to −15°) with a peak gain of 17.67 dBi within 1.3 dB variation over 57–64 GHz and a wide impedance bandwidth. A pair of LWAs is parallelly excited through a Y-power divider and terminated with the other end in series providing an additional 3 dB gain compared to the single LWA. Both designs show over 88% radiation efficiency and over 86% total efficiency. The fabricated prototypes of both antennas are made of multi-layered PCB technology. The measurement results show a good agreement with the simulations.
