The Performance Study of Microstrip Patch Antenna Made of Polyurethane - Oil Palm Empty Fruit Bunch Composite

Abstract

In this paper, the performance of microstrip patch antenna that is made of fully biodegradable materials has been studied. The polymer resins of Polyurethane as a binder agent were produced using polyol extracted from palm oil while the host composites were made from oil palm empty fruit bunch fiber. The performance of Polyurethane – Oil Palm (PolyOP) Empty Fruit Bunch composite as a microwave dielectric substrate was tested by fabricating microstrip patch antenna on it. The performance of fabricated patch antenna was measured using Vector Network Analyzer (VNA) and is compared with simulation results obtained from High Frequency Structure Simulator (HFSS) simulator. The difference of percentage in resonant frequency, return loss, bandwidth and VSWR between simulation and measurement were found to be 0.4%, 75.2%, 67.9%, and 12.7%, respectively.
