Circular Slot Antenna with Pattern Diversity
In this study, a dual-feed polarization diversity antenna with a broadside or conical radiation pattern is proposed. In the proposed structure, the radiator is designed based on a circular slot and is separated into two semi-circular slots using a protruding stub. Different radiation patterns can be...

| description | In this study, a dual-feed polarization diversity antenna with a broadside or conical radiation pattern is proposed. In the proposed structure, the radiator is designed based on a circular slot and is separated into two semi-circular slots using a protruding stub. Different radiation patterns can be implemented in the same frequency band by adjusting the phase difference applied to the two semi-circular slots. A modified 90° branch coupler was used as the feed structure. Analysis of the current and E-field distributions confirmed that there is a phase difference between the two semi-circular slots according to the input port. From the measurement results, the proposed antenna exhibited polarization diversity characteristics over the operating bandwidth, and the isolation between the two input ports was better than −30 dB. |
