Linear horn antenna with conical collar

A system comprising:

• a linear horn antenna with a linear horn body, a conical collar, and a plurality of antenna feeds;
• a plurality of ridges internal to a linear horn body of the linear horn antenna configured to generate electromagnetic fields including at least a first ridge, a second ridge, a third ridge, and a fourth ridge;
• wherein the conical collar is located on an exterior of the linear horn body at a first distance from a first end of the linear horn antenna, wherein the plurality of antenna feeds are located at a second end of the linear horn body that is opposite the first end;
• wherein the plurality of antenna feeds includes a first antenna feed and a second antenna feed, wherein the first antenna feed is isolated from the second antenna feed, wherein the first antenna feed is electrically connected to the first ridge and the third ridge, and where the second antenna feed is electrically connected to the second ridge and the fourth ridge;
• wherein the linear horn antenna is configured to generate one or more electromagnetic fields based on one or more excitation signals received via at least one of the plurality of antenna feeds;
• a memory having one or more computer readable instructions;
• at least one processor communicatively coupled with the memory and executing the one or more computer readable instructions stored in the memory is configured to:
• generate the one or more excitation signals;
• transmit the one or more excitation signals to at least one of the plurality of antenna feeds of the linear horn antenna;
• and
• generate one or more received signals at at least one of the plurality of antenna feeds based on one or more received electromagnetic fields.
