Incorporation of textile artificial magnetic conductor into dipole antenna

The radiation and gain characteristics of wearable dipole antenna which are omni-radiation pattern and low gain are not sufficient to support the wearable onbody system. So, to overcome these problems, the incorporation of textile dipole antenna with Artificial Magnetic Conductor (AMC) are designed...
