Single-feed Dual-band Dual-polarized textile antenna

Abstract

In recent years, many small antennas used near a human body have been proposed in the medical field. Most of them are designed in consideration of the influence of a human body having high dielectric properties and assume use at a single frequency or a single polarization. We proposed a dual-polarized textile antenna for the 5.2 GHz band as our previous study.

In this paper, we report the design of a dual-band dual-polarized antenna using single point coplanar feeding. This antenna has excellent radiation patterns and reflection coefficients for each of the desired frequency.
