Waveguide with slot antennas and reflectors

A system comprising:

• an antenna element;
• a device configured to transmit or receive electromagnetic signals via the antenna element, the device comprising:
• a plurality of waveguide channels, each waveguide channel including a hollow channel for a dielectric, the hollow channel including a plurality of slot antennas, each of the slot antennas comprising an opening through a surface of the waveguide channel that defines the hollow channel, each of the slot antennas being operably connected with the dielectric;
• a first plurality of reflectors, each of the first plurality of reflectors being positioned adjacent to and offset a first distance from a first longitudinal side of each waveguide channel;
• a second plurality of reflectors, each of the second plurality of reflectors being positioned adjacent to and offset a second distance from a second longitudinal side of each waveguide channel;
• and
• wherein first plurality of reflectors, the second plurality of reflectors, and the plurality of waveguide channels are arranged to produce a particular radiation pattern for the antenna element that is electrically coupled to the dielectric from a floor of the hollow channel of each waveguide channel.

A method comprising:

• forming a plurality of waveguide channels, each waveguide channel including a hollow channel for a dielectric, the hollow channel including a plurality of slot antennas, each of the slot antennas comprising an opening through a surface of the waveguide channel that defines the hollow channel, each of the slot antennas being operably connected with the dielectric;
• forming a plurality of reflectors;
• and
• assembling the plurality of waveguide channels and the plurality of reflectors onto a printed circuit board (PCB) to form a device configured to transmit or receive electromagnetic signals via an antenna element, the plurality of reflectors being positioned adjacent to and offset from each longitudinal side of each waveguide channel, the plurality of reflectors and the plurality of waveguide channels being arranged to produce a particular radiation pattern for the antenna element that is electrically coupled to the dielectric from a floor of the hollow channel of each waveguide channel, wherein two reflectors of the plurality of reflectors are offset an unequal distance from each longitudinal side of each waveguide channel of the plurality of waveguide channels.
