Abstract: “The paper highlights the possibility of using Polypyrrole (PPy) for planar microstrip patch antenna (MPA).The MPA has been designed using a conducting polymer PPy and PlexiglasTM laminate with a thickness of 1.8mm. The bulk conductivity of polypyrrole is 1200 and thickness is taken as 90mm.An analogous structure is designed using copper patch validating the design and comparing the performance. The antenna was designed for operations at 5.8 GHz. The PPy structure shows a gain of 4.6dB in contrast to 4.8dB gain of Cu structure. A comparative analysis is done between performance characteristics of Cu and PPy material fabricated on Plexiglas substrate results with good performance of PPy material. The result obtained confirms the advantage of using polymer materials in microwave applications as compare to the copper generally used.”
