High Gain and Fixed Broadside radiation at 140GHz Band by a Leaky Wave Slotted Waveguide
Paper i proceeding, 2022

In this paper a new topology for high gain antenna aperture with fixed broadside radiation is presented for 140GHz band. In the proposed structure, two symmetrical sets of leaky wave radiating slots are placed back to back on the broad wall of a metal parallel plate waveguide. A Corrugated surface is also applied in the feeding waveguide in order to deal with the grating lobe problem. The designed aperture provides proper fixed broadside radiation with 27.8-30.2dBi directivity over 142-148GHz frequency band. The aperture efficiency of more than 60% up to about 80% is also obtained over the most of desired band.
