Numerical and experimental generated data during project https://doi.org/10.1109/JIOT.2025.3599186

The dataset was generated during a project aimed at developing a miniaturized dual-band, dual-port MIMO implantable antennadesigned for wireless capsule endoscopy (WCE) and deep tissue applications. The antenna is integrated within a capsule-typedevice and has compact dimensions of 11.5 × 6 × 0.6 mm3. It operates in the Industrial, Scientific, and Medical (ISM) bands of 433.1–434.8 MHz and 902–928 MHz. The proposed antenna supports the transmission of high-quality images and video over a considerable distance. Miniaturization and high isolation are achieved using carefully designed meandered lines. This design avoids the use of shorting vias or ground-plane slots, which simplifies the structure and reduces back radiation. As a result, it eliminates the need for a complex decoupling network to enhance isolation. This antenna is the first reported MIMO implantable design to operate in the lower ISM bands while maintaining an ultra-compact size.
