Four-Aperture Multi-Port Rectangular Waveguide Antenna with Dielectric Resonator for Decoupling

抄録

Multi-port rectangular waveguide antennas with multiple feeds are proposed in this paper. The antennas consist of a traditional WR-28 waveguide and couple of feeding probes that are set in a line opposite direction. Flexible feeding strategies can be chosen in different applications. Four apertured rectangular waveguide antennas with a different number of ports （one port, two ports, three ports, and four ports） are designed at the center frequency of 28.5 GHz.　However, coupling between the opposite ports is higher than acceptable level therefore DR material integrated to four apertured structure for decoupling is proposed.
