Waveguide with squint alteration
This document includes techniques, apparatuses, and systems related to a waveguide with squint alteration, which can improve electromagnetic wave operation. In aspects, squint of electromagnetic waves pertaining to waveguides may be altered and improved. In this example, the techniques also enable the waveguide to direct electromagnetic waves according to respective chambers and one or more apertures, improving the quality of signals transmitted and received. The chambers may be divided according to a divider extending toward an opening of the waveguide, directing electromagnetic waves between the opening and the one or more apertures.
