Frequency and Pattern Reconfigurable Wideband Monopole Antenna for ISM Band Applications

This manuscript investigates a linearly polarized frequency and radiation pattern reconfigurable wideband antenna using two number of PIN diodes for achieving three distinct operation frequency for three different combinations of active diodes to switch between different frequency bands, including popular wireless communication frequency bands also used for ISM and IoT band applications. The proposed design exhibits pattern reconfiguration at two different angles for beam scanning. High frequency structure simulator (HFSS) is used to design and optimize the antenna. The compact monopole has dimensional measures of 59mm × 39mm × 1.6mm and has wide bandwidth coverage from 2.04 GHz to 3.26 GHz due to its two major and minor branches like structure thus making it apt for WiMAX and S-band applications.
