Thedesign and fabrication of a coupler with three reconfigurable output ports have been proposed.The output ports of the proposed\ncoupler can be adjusted by varying the number of shorting pins. An antenna with a reconfigurable beamwidth has been also involved\nin this paper. The proposed antenna has a coupler and a 1 Ã?â?? 3 array rectangular patch.The beamwidth is set by the number of output\nports.The simulation and experiment show the verification of the proposed coupler and beamwidth variation of array antenna.The\nbroadest measured beamwidth was 66.2âË?Ë? and the sharpest measured beamwidth was 24.1âË?Ë?.
