Summary:
A reconfigurable beam shape radiation pattern microstrip antenna is initiated in this paper. The antenna?s radiating surface is designed using a radial line slot array (RLSA) arrangement, which is fed from an aperture coupled structure. This novel feeding structure for an RLSA antenna incorporates PIN diode switches which are integrated with the feed line structure to enable the variety outcomes of the radiation patterns. The circular arrangement of slots at the radiating surface, contributes to the reduction in size of the proposed antenna compared to conventional microstrip antenna that can yield the same antenna gain. The proposed antenna design operates at 2.3 GHz frequency band, and has a maximum gain of 13.8 dB. The proposed antenna has an enormous potential for point-to-point and point-to-multipoint communication and WiMAX application.
