Abstract In this paper, a miniaturized implantable antenna system for biomedical applications is presented. The system consists of almost two similar patch antennas, named internal and external. The internal antenna is implanted inside the body at a depth of 2 mm, and the external antenna is to be attached to the body aligned with the internal one. The antenna system consists of implant-side antenna with dimensions are 10.25×10.25×1.27 mm3 , while the external antenna dimensions are 11.1×11.1×1.27 mm3. The proposed antennas designs showed dual resonant frequency on ISM bands (ie , 915 MHz and 2450 MHz ). The computed -10 dB bandwidth considering three-layer human phantom demonstrates that a bandwidth of 870 to 970 MHz and 2.38 to 2.47 GHz for internal and external antennas are achieved. The Specific Absorption Rate (SAR) has been considered for health care consideration. The measured and simulated scattering parameters are compared, and good agreements are achieved. The proposed antenna system is simulated and investigated for biomedical applications suitability.

Implantable Antenna

A novel coplanar waveguide fed Industrial, Scientific, and Medical (ISM) band implantable crossed-type triangular slot antenna is proposed for biomedical applications. The antenna operates at the center frequency of 2450 MHz, which is in ISM band, to support GHz wideband communication for high-data rate implantable biomedical application. The size of the antenna is 78 mm3 (10 mm × 12 mm × 0.65 mm). The simulated and measured bandwidths are 7.9 and 8.2% at the resonant frequency of 2.45 GHz. The specific absorption rate distribution induced by the implantable antenna inside a human body tissue model is evaluated. The communication between the implanted antenna and external device is also examined. The proposed antenna has substantial merits such as miniaturization, lower return loss, better impedance matching, and high gain over other implanted antennas.
