Design and Analysis of Conducting Polymer based Microstrip Patch Array Antenna for Wi-Max Applications

Abstract

In this research work proposes the design and analysis of conducting polymer based microstrip array antenna which is operated at a frequency range of 3 GHz to 3.6 GHz for Wi-Max applications. Here, the conducting polymer is taken as the patch material due to its high conductivity, flexibility, reproducible and cheaper than normal conductors. Three different shapes like H, U and S shaped slots are included in MSPA design and the return losses are noted for each design with the use of ADS software. Proposed Polypyrrole (PPy) antenna is designed on FR-4 substrate which provides compactness to antenna and can be embedded easily in any devices.  Return losses of PPy based MSPA with different types of slots are measured and compared with standard metallic antennas.   The results indicate that it is possible to obtain reasonable performance with higher gain, wide bandwidth and higher efficiency as similar to that of metallic antennas.
