수직 모노폴 방사패턴을 갖는 인체표면 통신용 평면형 안테나 설계

초록

In this paper, a planar antenna with monopole-like radiation pattern for on-body communications is proposed. The proposed antenna consists of three split-rings(SR) to generate a monopole-like radiation characteristic. To account for the on-body application, the proposed antenna is designed to have a low-profile. The antenna has an overall dimensions of 0.29 λ0×0.29 λ0×0.008 λ0 at 5.8 GHz industrial, scientific, and medical(ISM) band(5.725～5.875 GHz). To verify the body effect, a two-thirds muscle equivalent semi solid phantom is fabricated and used to measure the antenna performance. The 10-dB return loss bandwidth is 280 MHz(5.68～5.96 GHz) and the measured peak gain is 1.91 dBi.
