Queen's University introduces innovative antennas

Experts at Queen's University, Belfast, UK have introduced a new type of antenna that is up to 50 times better and efficient than the existing designs. The new design is capable of utilising 'wireless body area network' (WBAN) technology to full potential. A WBAN is a network of biosensors attached to different parts of a patient's body.

These antennas are designed to heighten and control the 'creeping wave effect' by maximising the amount of signal radiated to the antenna's side, rather than inwards and outwards. As a result, the signal creeps on the human body and can be picked up by the antennas that can transmit information via radio signal to a control unit placed on patient's body. The doctors, via Internet or a cellular phone, can access this data. This helps them in arranging appointments when needed, thus reducing the number of visits for tests and check-ups. Furthermore, it allows patients wearing a WBAN to carry on with their normal lives.

The new antenna is 5mm thick, which is almost one-sixth of the available thickness. This makes it convenient to fit them anywhere on the patient's body. The strength of signal transmitted by the new antennas has no health or safety implications for humans. The technology is still in the development stage and is expected to be available in five years' time.
