In this letter, two skin-implantable biotelemetry devices are presented along with an antenna system that operates on five bands, including the Medical Implant Communication Service (MICS) (402-405 MHz) and the Industrial, Scientific, and Medical (ISM) (433.1-434.8 MHz, 868.0-868.6 MHz, 902-928 MHz, 2400.0-2483.5 MHz) bands. A link budget analysis was used to configure an algorithm for effective device operation. These devices contain space for storage batteries, controlling electronics, and bio-sensors, along with a planar inverted-F antenna (PIFA), and have total volume of 617 and 510 mm3respectively. These devices were primarily designed and simulated in different environments with FDTD software. In addition, the performance of the antenna system was evaluated from measurements made inside a skin-mimicking semi-solid homogeneous phantom. This research shows that multi-channel communication will enhance the diversity of biotelemetry devices.
