Abstract

This research showcases a novel ultra-compact antenna for biomedical implants operating at the 2.45 GHz Industrial, Scientific, and Medical (ISM) band. It features a small footprint of 1.27 mm³, measuring 3.3 × 3.3 × 0.12 mm³, achieved through a resonator patch with a meandered design on a high-permittivity substrate for efficient miniaturization. Testing the antenna within a phantom box that contains muscle, fat, and skin shows a maximum gain of -23.6 dB at 2.45 GHz, highlighting its satisfactory performance given its small size. The antenna also exhibits omnidirectional radiation patterns. Additionally, the antenna's specific absorption rate (SAR) analysis confirms its safety. These findings underscore the antenna's practicality, versatility, and potential for integration into various biomedical applications.
