Design and Analysis of a Compact 28 GHz Textile-Based Antenna for Wireless Body Area Network

This research paper presents a novel design of a 28 GHz textile-based antenna for Wireless Body Area Network (WBAN) applications, with Panama textile material as the substrate. The proposed antenna’s design capitalizes on the unique properties of Panama fabric, which offers both flexibility and durability, making it suitable for integration into clothing. Computer Simulation Technology (CST) software was utilized to simulate and design this antenna. The physical dimension of the Panama substrate is 9mm x 6mm x 1.04 mm. Copper conductors are used to design the antenna and the ground plane. -32.56 dB is the antenna’s reflection coefficient at 28 GHz. With a radiation efficiency of 81%, the antenna has a gain of 5.2 dBi. In the CST software, a three-layer human body facsimile was created in order to assess the antenna’s effectiveness on the human body. The results were analyzed while the antenna was 6mm from the human body facsimile. This antenna performs admirably in free space and on the human body.
