Frequency reconfigurable microstrip patch antenna for multiband applications

Abstract

Wireless communication is a well-established technology for which several types of antennas have been developed specifically. However, antenna performance and communication system development need to be enhanced to adapt to the present era. The performance of the antenna is significantly influenced by its design. As a result, this work developed a novel wideband antenna design using a frequency reconfigurable approach. Shunt-series microelectromechanical systems (MEMS) were used in the proposed study to switch frequencies in wideband applications using microstrip patch antennas (MPAs). The suggested antenna with two integrated switches is tested in ON-ON, OFF-ON, and OFF-OFF switching scenarios. A range of antenna performance metrics, including as gain, bandwidth, return loss, radiation pattern, and voltage standing wave ratio (VSWR), are used to assess the suggested antenna's performance in each switching situation. The simulation's findings indicate that the ideal antenna design for wireless communication systems is one that works well with a shunt-series MEMS switch.
