Design a PIFA Antenna for Healthcare Application

Abstract

In the modern era, satellite and wireless communication systems have become integral to an individual's daily life, particularly within the medical and communication sectors. This chapter presents the design of a planar inverted-F antenna (PIFA) specifically tailored for health-care applications. PIFA antennas are renowned for their low cost, low profile, and high performance over a wide frequency range, making them ideal for integration into biomedical devices. The proposed antenna is designed to resonate at 403 MHz, which falls within the medical implant communication services (MICS) band (402-405 MHz). Utilizing an FR-4 substrate, the antenna achieves a compact size of 12.8 x 12.8 x 0.8 mm3, optimized for in-body implantation. The simulation results demonstrate a bidirectional radiation pattern, ensuring reliable performance. Additionally, the specific absorption rate (SAR) values are well within the established safe limits, making this design suitable for continuous use in medical implants. This combination of features positions the PIFA as a highly effective solution for modern health-care applications, offering both safety and efficiency.
