Abstract
A wearable textile antenna with dual-band and dual-sense characteristics is presented in this work. It operates at the 2.45 GHz band for WBAN and WLAN applications, and at the 1.575 GHz band for Global Positioning System (GPS) applications. An antenna backing based on an artificial magnetic conductor (AMC) plane operating at 2.45 GHz band is introduced to reduce the backward radiation and to improve antenna gain. It consists of a $3\times 3$ array of square patch unit cells, where each unit cell is integrated with four square slits and a square ring. A square-shaped patch is then located on top of the substrate as its radiator. To enable dual-band operation, two corners of this radiator are truncated, with each of the four corners incorporated with a rectangular slit to enable its circular polarization characteristic in the GPS band. Simulation and experimental results are in good agreement and indicate proper antenna operation with linear polarization in the 2.45 GHz band and circular polarization in the 1.575 GHz band, with realized gain of 1.94 dBi and 1.98 dBic, respectively.
Highlights
Research on wearable antennas has been intensive in recent years due to its huge potential generated for integrating wireless capability into clothing
A wearable textile antenna with dual-band and dual-sense characteristics is designed for location tracking purposes, using Global Positioning System (GPS) in the outdoor and WLAN in indoor environments
The dual band radiator originated from a square patch before being integrated with slits and truncated corners to operate in the 1.575 GHz band and in the 2.45 GHz band
Summary
Research on wearable antennas has been intensive in recent years due to its huge potential generated for integrating wireless capability into clothing. Textiles has been the preferred material due to their comfort, light weight, high flexibility, and ease of integration with clothing [1]. Such implementation is especially useful in location tracking especially in search and rescue, and long-term patient monitoring [2]. Outdoor for wireless localization: using WLAN for the former, and using the Global Positioning System (GPS) for the latter, using a single antenna This technology merging using a single wearable device based on textile technology is highly cost-effective, besides improving the comfort for the user [1]. One of the effective methods in reducing the SAR level is by shielding
