Design, Simulation and Mathematical Modelling of Slotted Microstrip Patch Reconfigurable Antenna Array for Future Wireless Communication

A multi-slotted Microstrip frequency reconfigurable antenna is designed-simulated and analyzed in this paper for MIMO applications. The antenna demonstrates the impact of parasitic patches, Slots, and PIN diode on the radiating surface. Designed to operate at five frequencies 3.7 GHz/ 5 GHz/ 6 GHz /9.8 GHz with S11 < -10 dB and VSWR < 2. The communicating bands and the bandwidth achieved by the reconfigurable antenna are 3.72 - 3.8 GHz / 2.1% bandwidth, 4.89 – 5 GHz / 2.2% bandwidth, 5.85 – 6.28 GHz / 7.2% bandwidth, and 9.63 – 9.97 GHz / 3.4% bandwidth. The antenna holds potential applications in areas such as Cognitive radio, C and X band (Microwave communications), MIMO, WiMAX, Satellite Communication, etc.
