Abstract
In this paper, two miniaturized flexible wearable antennas based on a planar dipole with a reflector are proposed and investigated. To realize miniaturization, the concept of magneto-dielectric (MD) composite materials was chosen. Numerical and experimental analyses were carried out to investigate the antenna performance (radiation efficiency, gain, and bandwidth) in the free space and on a tissue-equivalent phantom. Results demonstrated that MD composites are beneficial for wearable antenna miniaturization (up to 36%) and radiation efficiency improvement (up to 65% in free space and up to 23% on-body). Moreover, the antennas exhibit a low specific absorption rate.
