waveguide slot

waveguide slot

[′wāv‚gīd ‚slät]
(electromagnetism)
A slot in a waveguide wall, either for coupling with a coaxial cable or another waveguide, or to permit the insertion of a traveling probe for examination of standing waves.

By applying the proposed switchable metasurface for a waveguide slot array antenna, the antenna array factor can be controlled, and then the radiation pattern can be steered.
Filtering antennas have been implemented in different forms including rectangular patch [1], circular patch [2], patch array [3], T-shaped antenna [4], slot dipole [5], monopole antenna [6], inverted-L antenna [7], Yagi antenna [8], waveguide slot antenna [9], and dielectric resonator antennas [10].

In this article, the designs of two different types of compact planar magic tee junctions -- a planar magic tee junction (PMTJ1) using a collinear transverse waveguide slot coupler and a planar magic tee junction (PMTJ2) with a longitudinal/transverse slot coupled difference port -- have been accomplished based on MoM analysis and FEM-based CAD high frequency structure simulator software (HFSS).
