Abstract :
A dual-band textile antenna loaded with metamaterials is proposed and analyzed. By introducing a composite right/left-handed transmission line, similar field distributions and radiation patterns are obtained in the two operation bands. The antenna is calculated on a human tissue model for both planar and bending situations. The antenna performance, e.g. resonant frequency, impedance matching bandwidth, directivity, gain, radiation efficiency, and specific absorption ratio (SAR), are compared. This verifies the antenna robustness and safety for use on a human body.
