Abstract
In this paper, a low-profile dipole array antenna with monopole-like radiation for on-body communications is proposed. The proposed antenna, operating in the industrial, scientific, and medical (ISM) band, is designed with consideration of the human body effect. By placing eight planar dipole antenna elements symmetrically around the z-axis, the proposed antenna achieves monopole-like radiation characteristics with a low profile. The antenna has overall dimensions of $0.44{lambda}_0{times}0.44{lambda}_0{times}0.013{lambda}_0$ at 2.45 GHz in the ISM 2.45 GHz band (2.4-2.485 GHz) and a 10-dB return loss bandwidth of 4.9% ranging from 2.4 to 2.52 GHz.
Key words: Low Profile, On-Body Antenna, Monopole-Like Radiation, Wireless Body Area Network (WBAN)
