Design of a Reconfigurable Dual-Band Slot Antenna with MEMS Switches

Today, there is a great need for multipurpose, reconfigurable antennas due to variety of applications. The simulated design for a reconfigurable dual-band slot antenna with dynamic polarization control based on MEMS switch is shown here. Proposed antenna can flip between linear and circular polarization modes and works in two different frequency such as 2.4 GHz and 5 GHz frequency bands. A rectangular patch with FR-4 Epoxy dielectric material is designed initially. Further, the circular patch is with annular slot is placed within it. MEMS switches, can change the network and slot configuration to enable dual-band operation and polarization diversity, are used to accomplish this. Performance of the proposed antenna, offering information about design factors for next generation wireless communication systems. The result section switching frequencies are shown are notches in return loss diagram. Also, the radiation pattern for these two frequencies is shown in result section.
