ABSTRACT: In this paper, high directive antenna using
metamaterial property is presented for wireless medical systems. The antenna is
constructed by semi-circular patch and hexagonal closed ring resonator (HCRR).
For medical applications such as wireless patient movement monitoring,
telemetry and telemedicine, communication devices working at ISM band frequency
is needed. Here, the requirement is completed with improved directivity such as
16 dBi. And also impedance matching also achieved with low reflection loss -20
dB. This antenna works for multiple frequency bands (Industrial, Scientific and
Medical-ISM 2.45 GHz, WLAN 5.3 GHz and GSM 1.9 GHz) with improved directivity.
