Abstract
This paper presents the design and fabrication of WR-28 waveguide horn antennas operating in the Ka-band frequency range between 26.5 GHz and 40 GHz through 3D printing. Three different antennas are fabricated from polylactide acid filaments in conductive and non-conductive variants; the latter is covered with conductive paint. The gain and voltage standing wave ratio performance of the fabricated horn antennas is measured in a vector network analyzer, showing promising performance. Antenna gain values between 5 dBi and 14 dBi are found, comparable to the performance of metal milled horn antennas
