Abstract:
This research work is conducted to design and analyze a novel antenna for In band full duplex
communication. A metamaterial-based microstrip patch antenna is designed for wideband
operation in IBFD systems. The design incorporates electromagnetic band-gap structures for
improved isolation and bandwidth enhancement. Detailed mathematical modeling and full-wave
simulation techniques are employed to optimize the antenna's performance. Designed antenna in
the 4.9 GHz to 6.4 GHz range, with a focus on achieving high isolation (over 40 dB).Peak isolation
is 55 dB and increased up to 67 dB with rat race coupler. Grid slotted patch antenna and thick
substrate reduces the surface wave coupling and enhances the isolation. T structure feeds also
enhances the DC isolation due to gap between the structure and radiating element. The simulation
results show excellent isolation and impedance matching across the target frequency band
