Miniaturized and Flexible Dual-Band Antenna Based on Open-Ended Slots for Wi-Fi/ISM and Wearable/Portable Application.

This paper presents the miniaturized and flexible antenna, design on textile material based on the open-ended slot for portable and wearable applications. The jeans substrate is used with an optimized feed position of the miniaturized antenna where the two orthogonal open-ended slots are accomplished on the ground and patch to obtain the dual bandwidth and miniaturization in size. The overall size of the textile antenna is 12 mm × 12 mm with 10 dB bandwidth from 4.9 to 5.05 GHz (Wi-Fi) and 5.7 to 6 GHz (ISM bands) with positive realized gain where the compact size of the antenna covering both important bands for wearable and portable applications.
