2020 International Symposium on Antennas and Propagation (ISAP).
This paper presents a low side-lobe slotted ridge waveguide array manufactured by resin injection molding. The resin waveguide is divided into two parts, and both are fastened using screws and bosses. The waveguides need to be arranged closely in ord
