Abstract

The aim of this study is to present a dual-band antenna for Wireless Medical Telemetry Service (WMTS) applications. The antenna covers all three frequency bands 608-614 MHz, 1395-1400 MHz, and 1427-1432 MHz, and is intended for continuous health monitoring of patient's vital parameters. The designed antenna consists of a meandered dipole antenna and a superstrate layer to preserve the biocompatibility of the structure. It has a compact size with dimensions 17.6 mm x 12 mm x 2.54 mm. The measured -10 dB bandwidths are found to be 16.3% for the lower frequency band and 10.6% in the upper frequency band. The antenna is in vitro tested in a tissue mimicking solution.
