A small-size and multi-band wearable antenna with coplanar structure
Abstract
A small-size multi-band wearable antenna with coplanar coupling of radiation patch and ground plane for 4G mobile communication is proposed and discussed in this paper. A coupling strip, a C-shaped slot made of copper foil and a shorting strip are combined to form the proposed wearable antenna with a simple structure and small size of 25×32 mm2. The proposed antenna operates over two frequency ranges, 2308-2841 MHz and 5092-5887 MHz suitable for LTE 2300/2500 MHz, WLAN 2.4/5.2 GHz and ISM 5.8 GHz applications. In addition, the proposed antenna has better stability and it also can cover five frequency bands when the curvature radius is 45 mm and 25 mm in comparison with traditional conductive fabric wearable antennas. The designed antenna is easy to fabricated, small in volume and wide in frequency band that is applicable to most wearable electronic devices in the future.
