A new broadband dual polarized L-shaped horn antenna and associated waveguide feed structure is presented. The horn antenna and waveguide feeds are filled with dielectric material, where a small aperture area of 0.5lambda square is achieved. Using stereolithography, the miniature antennas and waveguides were fabricated as sets of cavity filled blocks. Broadband attributes are demonstrated with a measured return loss of better than -10 dB from 34 to 40 GHz. The measured gain is 5.3 dB at 35 GHz, with 19 dB cross-polarization discrimination
