Abstract

This paper introduces the development of an antenna model with a meandering shape in the industrial, scientific, and medical band (i.e., 2.4-2.48 GHz) proposed for biomedical applications. This design is specifically tailored for stimulation applications, where size and form factors are critical. The design of the meandering patch antenna seeks to optimize performance while ensuring compatibility with the unique requirements of stimulation devices. A Rogers RO3010 (loss tangent = 0.0022, relative permittivity = 10.2) is used in the design as a substrate. The miniaturized antenna (2.5 mm × 2 mm × 0.12 mm), featuring a 400 MHz bandwidth, was engineered to mitigate detuning effects caused by electronic interference and biological tissue heterogeneity. The smaller dimensions of this antenna not only facilitate easier integration within device structures but also aim to enhance characteristics such as impedance matching and bandwidth, addressing the challenges posed by the confined space within the human body. The proposed antenna also exhibits a -33 dB gain and a lower specific absorption rate (SAR) of 272 w/kg. These attributes position it as a promising solution for biomedical implantation.
