Abstract

This paper presents a low-profile multiple-input multiple-output (MIMO) implantable antenna system including a capsule endoscopy and a scalp implantation at Medical Implant Communication Service (MICS) band (402–405 MHz), and Industrial, Scientific, and Medical (ISM) band (433.1–438.8 MHz). It consists of two elements with an edge-to-edge gap of 0.0018λg and overall dimensions of π × (5.65)2 × 0.13 mm3 and is placed on a 0.13 mm thick RO3010 (ϵr = 10.2, tanδ = 0.0022) substrate. The antenna is integrated with batteries, sensors, and electronic components in two different types of implantable devices (capsule and flat-type devices). The simulation result shows that the antenna has a fractional bandwidth (FBW) of 33.9%, a maximum realized gain of -30 dBi, and isolation of more than 26 dB. The fabricated prototype is measured in a saline solution and minced pork meat. The measured results are found in good accordance with simulations. The antenna parameters are calculated and showed a significant independence between the radiators. A link budget is estimated to be 78 Mb/s for a distance of 20 meters. Thus, the proposed antenna is considered as a promising solution for high data-rate medical applications such as capsule endoscopy, live surgeries, and other biomedical applications where the high data-rate is required.
