Abstract—The paper proposes and investigates a linear waveguide-slot antenna array with a 180° frequency scanning sector, made in the form of a rectangular metal waveguide filled with a dielectric with periodically arranged pairwise transverse slots in a wide wall. In the frequency band corresponding to a single-mode waveguide, the waveguide-slot array in the low-frequency part of the range emits at a zero spatial harmonic, and in the high-frequency part, at the minus first harmonic. An approximate theory is used to determine the waveguide parameters that satisfy the frequency scanning requirement in a 180° sector. The results of the approximate theory are confirmed on the whole by the results of numerical simulation of the scanning characteristics using a finite element method.
