Abstract
Examples disclosed herein relate to a multi-frequency electromagnetic feed line. The multi-frequency electromagnetic feed line includes a waveguide that has a plurality of slots arranged laterally along a length of the waveguide that corresponds to a first axis, in which the plurality of slots are configured to radiate electromagnetic signaling from an input end of the waveguide to a terminal end of the waveguide. The waveguide also has a plurality of vias arranged proximate to the terminal end of the waveguide in a predetermined angle relative to a second axis orthogonal to the first axis, in which the plurality of vias are configured to terminate the plurality of slots for different frequencies of an operating frequency band. A first slot of the plurality of slots that is arranged closest to the terminal end has varying distances to different vias. Other examples disclosed herein relate a method of fabricating a waveguide.
