| Summary: | This paper proposes the design of Balun Control Feed Antenna (BCFA) using four different mixtures of biocomposite. The design covered the IEEE 802.11b (2.412-2.472 GHz) standard that has thirteen channels, which consist of the parasitic patch (first substrate) and Quarter wave Balun with partial ground (second substrate) and Air Gap separation. To analyze the substrate performance, the resonant frequency was controlled by tuning the Balun and the quarter wave structure, while other dimensions were fixed. The antenna gain reported a decay with the increments of the filler mixture (4.62 to 0.1dBi) while FR4 (1.83 dBi), which resonant frequency occurs between 2.43 to 2.46 GHz. The changes in the gain, bandwidth, frequency response and directivity occur since the loss tangent increased in parallel with the filler composition mixture. The results of the measurement and simulation were demonstrated back to back to emphasize the performance of the proposed four different combination substrates with a direct comparison to FR4. © 2017, Universiti Teknikal Malaysia Melaka.
