The Electronic Ceramics research group at the Philips Research Laboratories in Aachen say that they have succeeded in developing the world’s smallest antennas for mobile communications.
The Philips mini antennas are approximately eight times smaller than conventional antennas and deliver comparable performance.
A number of telephone manufacturers are already using antenna designs based on a combination of plastic and metal that are concealed in the housing of the phone. However, this necessitates a new, specific antenna design for each new generation of telephones and, furthermore, the antenna still requires a lot of space.
The Philips mini antennas only require a fraction (1/8) of this volume. Thanks to their standardised design, they can be built in to the top of each handset.
In addition to their use in mobile phones, Philips also expects to see a market for them in ‘radio modules’ – devices that are used for cordless data transmission between a mobile phone and computer, or from one computer to another in a Local Area Network.
