This paper presents the use of machine learning (ML) to facilitate the design of dielectric-filled Slotted Waveguide Antennas (SWAs) with specified sidelobe levels. Conventional design methods for air-filled SWAs require the simultaneous solving of complex equations to deduce the antenna’s design parameters, which typically requires further manual...

Slotted waveguide antennas (SWAs) are widely used in high power microwave applications. In this paper, the slots displacements in broadwall SWAs, previously used to control the SWA sidelobe level ratio (SLR), are further investigated to also adjust the beamwidth of the SWA. A modified Taylor array design method is used to estimate the excitations o...

This paper presents a procedure for the design of a 2D Slotted Waveguide Antenna (SWA) array having circular polarization. The 2D array is formed by a defined number of 1D branchlines broadwall SWAs, which are fed using an extra broadwall SWA. The SWA branchlines have cross-shaped slots that radiate with a circular polarization. The dimensions of t...
