Experimental Verification of 3D Metal Printed Dual Circular-Polarized Horn Antenna at V-Band
In this paper, a 3D metal printed dual circular-polarized horn antenna operating in the V-band is proposed, built and tested. This antenna consists of a horn and a circular waveguide, a single groove polarizer and is side-fed by orthogonally placed rectangular waveguide ports. The groove is placed at 45° with respect to the input ports and provides a phase delay of 90° to generate right- or left-hand circular polarization (RHCP or LHCP). The proposed antenna provides symmetric patterns for all planes and exhibits polarization isolation of more than 30 dB at broadside. This antenna is analyzed to realize wide impedance matching bandwidth and wide 3dB axial ratio (AR) bandwidth. A prototype of the horn antenna has been fabricated using 3D metal printing technology. Metal material with finite surface roughness is considered when modeling this antenna.
