Superstrate loaded miniaturized patch for biomedical telemetry

Abstract

ABSTRACT A Superstrate loaded miniaturized patch antenna is proposed for biomedical applications. The targeted operating frequency is (902–928 MHz) ISM band with a center frequency of 915 MHz. The antenna is designed to operate in close proximity with human‐body with a size of 25 × 25 × 1.92 mm 3 . Parametric studies were conducted to specify the dominant parameters and to understand their effect on the antenna performance. Measurements show that the fabricated antenna resonates around 915 MHz with a 30 MHz impedance bandwidth. On‐skin measurement results are presented for several spots on the human‐body. Furthermore, the transmission coefficient (S 21 ) of the fabricated antenna is measured using lean beef slices with various thicknesses and showed good agreement with simulation results. © 2017 Wiley Periodicals, Inc.
