Abstract :
A microstrip patch antenna (MPA) has been fabricated using a conducting polymer, polypyrrole (PPy), as a ground plane. The bulk conductivity level of the PPy ground plane is 2000 S/m and its thickness is 330 mum. The antenna is designed to operate in the 11 GHz region. The measured and simulated results at the resonant frequency such as return loss, gain, radiation pattern and bandwidth are presented in comparison with a similar copper ground plane antenna. CST Microwave Studio was used as a design and simulation tool and experimental measurements of the antenna made to validate the simulations. The results show that a microstrip antenna with PPy as the ground plane provides a gain of 4.1 dB at 10.5 GHz as against 5.35 dB for copper ground plane at 11 GHz.
