2.4GHz Patch Antenna on Bio-Composite Substrate Using Quarter Wave Transmission Line

This paper presents a rectangular patch antenna which has been developed using new bio-composite substrate. The substrate is developed using Bambusa Vulgaris and High Density Polyethylene as bio-composite material. This patch antenna is purposely designed for wireless application which operates at 2.4GHz frequency band. The major intention of this paper is to reveal the performance of an antenna which is fabricated on the new bio-composite substrate in terms of dielectric constant, return loss, radiation pattern and gain values. All these measurements are completed through several experiments. The measured performances were compared with its simulation values. In addition, this patch antenna uses a rectangular patch as the radiating element. The antenna also uses a quarter wave transmission line technique to match the feeding line with its patch. The Bambusa Vulgaris rectangular patch antenna was initially designed via CST Studio Suite software prior to fabrication.
