WIRELESS COMMUNICATIONS DEVICE HAVING LOOP WAVEGUIDE TRANSDUCER WITH SPACED APART COUPLING POINTS AND ASSOCIATED METHODS

摘要

A wireless communications device may include wireless communications circuitry and a waveguide transducer coupled to the wireless communications circuitry. The waveguide transducer may include a loop electrical conductor having a plurality of spaced apart gaps therein defining a plurality of respective spaced apart coupling points. The waveguide transducer may also include a feed assembly that may include at least one waveguide feed, and a feed network coupled between the at least one waveguide feed and the plurality of coupling points. The waveguide transducer may further include a waveguide surrounding the loop electrical conductor and extending outwardly therefrom. The waveguide may include a tubular body having an open end and an opposing closed end carrying the loop electrical conductor.
