A Compact Frequency-Reconfigurable Antenna Using a Single PIN Diode for IoT and Sub-6 GHz Applications

This research article introduces a compact, frequency-reconfigurable microstrip radiating element featuring a PIN diode for multiband wireless communications. The proposed radiating element is simulated on an FR-4 substrate measuring 22.5 x 13 x 1.6 mm³ and is designed to operate below 6 GHz. The antenna design feature...
