The array is designed for integration inside a capsule to establish a stable, high data-rate multiple-input multiple-output (MIMO) wireless communication link for wireless endoscopy. The compact antenna (π× 1.125 ×1.49 mm3) uses stacked meandered resonators, nestled within an annular ring-shaped planar substrate, offering over 7 MHz bandwidth and 41 dB isolation. It achieves a 78 Mbps data rate over 1.6 m in muscle tissue with a specific absorption rate of 2 W/kg at 20 mW power. Measurements show an ECC below 0.001, diversity gain over 9.99 dB, and a channel capacity of 10 bps/Hz at 20 dB SNR. To the best of our knowledge, this is the first dual-camera-integrated MIMO antenna system for the [401-406] MHz MedRadio band tested in an implantable device.Journal article10.1109/JERM.2024.3501385WOS:001371970100001POWER TRANSFER SYSTEMSMALL-BOWELDESIGNPROPAGATIONEFFICIENCYBANDSLINKMHZ
