Researchers from Queen Mary University of London have achieved a major milestone in medical technology with the development of a novel dual-camera-integrated MIMO antenna system designed for high-data-rate wireless capsule endoscopy (WCE).

The paper, published in the IEEE Journal of Electromagnetics, RF, and Microwaves in Medicine and Biology (September 2025), introduces an ultra-compact antenna array that enables capsule endoscopes to transmit high-quality video data from deep inside the human body with unprecedented reliability and speed.

The interdisciplinary research team; Dr Muhammad Qamar, Dr Kamil Yavuz Kapusuz, Dr Lawrence Carslake, Dr Tian-Hong Loh, Dr Mohamed A. Thaha, and Professor Akram Alomainy, designed a two-port multiple-input multiple-output (MIMO) antenna that operates within the 401–406 MHz MedRadio band. The design integrates two cameras and achieves a data rate of 78 Mbps through 1.6 metres of biological tissue, maintaining excellent isolation and safety standards.

Unlike traditional single-camera capsule endoscopes, this dual-camera design captures simultaneous front and rear views of the gastrointestinal tract, enhancing diagnostic accuracy and reducing the need for repeat procedures. The innovative antenna structure is built using standard multilayer PCB technology, making it small, manufacturable, and ready for real-world integration.

Professor Akram Alomainy, co-author of the paper and project lead, said:

"This work brings us closer to the next generation of intelligent, high-speed medical capsules that can provide doctors with clearer, more comprehensive views of the human body while improving patient comfort and safety."

The research combines cutting-edge electromagnetics, biomedical engineering, and clinical collaboration, supported by the European Partnership on Metrology (21NRM03 MEWS Project) and Horizon Europe funding.

This achievement places Queen Mary at the forefront of wireless biomedical innovation, paving the way for smarter, faster, and more reliable implantable medical devices.
