Design of a Coupler with Three Reconfigurable Output Ports and a Beamwidth Reconfigurable Antenna

الملخص EN

The design and fabrication of a coupler with three reconfigurable output ports have been proposed.

The output ports of the proposed coupler can be adjusted by varying the number of shorting pins.

An antenna with a reconfigurable beamwidth has been also involved in this paper.

The proposed antenna has a coupler and a 1 × 3 array rectangular patch.

The beamwidth is set by the number of output ports.

The simulation and experiment show the verification of the proposed coupler and beamwidth variation of array antenna.

The broadest measured beamwidth was 66.2° and the sharpest measured beamwidth was 24.1°.
