Denim-Based Wearable Textile Patch Antenna for 2.45 Ghz Frequency Band

Abstract

The rapid downsizing of wireless devices has accelerated the use of wearable textile materials as antenna substrate. Incorporating textile antennas allows users to maintain good communication link quality while not carrying bulky gear. Flexible antennas are attached onto fabric, making them unnoticeable while being positioned well to send and receive signals. This is useful in many applications including mobile computing and public safety. Micro strip patch antennas have been shown to work particularly well for body-worn applications because their ground plane effectively shelters the human tissues and they mostly radiate perpendicularly to the planar structure. This study examines wearable patch antennas in a C-shape that were created and optimized for 2.45 GHz applications. The patch antenna is designed and simulated using CST based on the design by [1], with modification to increase the frequency coverage and bandwidth.
