A metamaterial-inspired frequency reconfigurable antenna with switchable polarization, realized for 2.4 GHz, 3.5 GHz and 5.8 GHz frequencies, is reported in this work. Initially, a conventional rectangular patch is designed to resonate at 3.5 GHz. A regular square shaped SRR (Split Ring Resonator) is the metamaterial-inspired structure used to excite additional resonance at 5.8 GHz, without increasing the form factor of antenna. Further, a parasitic patch is introduced to create one resonance at 2.4 GHz. Reconfigurability of frequency and polarization is achieved using MPP4203 series PIN diodes. The antenna is simulated using CST Microwave Studio Suite 2019. The designed antenna, characterized in terms of reflection coefficient and bandwidth is analyzed for three different diode states. The devised antenna operates at 2.4 GHz, 3.5 GHz and 5.8 GHz, with a maximum bandwidth of 346.2 MHz at 5.8 GHz frequency band. The radiator outperformed other similar antennas reported in literatures in terms of antenna size, bandwidth and frequency cum polarization reconfigurability.
