Low-profile antennas for on-body surface communications

In this paper, low-profile antennas for on-body surface communication are introduced. A circular-ring patch antenna with TM
₃₁
higher order mode for monopole-like radiation characteristic with low-profile in ISM 2.45 GHz band is proposed. A center-fed circular patch antenna with corrugated ground for surface wave guide in ISM 5.8 GHz band is also proposed.
