The Development of Miniaturized Wearable DRA with a Wideband Circular Polarization

Abstract

: In wireless communication, wearable technology has increased rapidly due to its higher demand in various industries with the benefits of the unconstrained movement freedom a Wireless Body Area Network (WBAN) offers. However, to design a wearable antenna is challenging due to the antenna that must be designed in a compact size with the ability to transmit low power loss during transmission and maintaining the performances of the communication link. In this research project, the antenna is designed singly feed and in a spiral shaped conformal copper strips are used to excite the DRA. The simulated result by CST software stated that S11 below -10 dB is 6.66% with Axial Ratio below 3dB is approximately 5.26%. A prototype antenna is fabricated to validate the simulation result. Hence, the antenna design is beneficial for many people in improving human productivity in daily life in the evolution of WBAN.
