Ether 1.3.1 phone adaptive antenna solution integrates with smartphones!

July 14, 2011

San Diego, USA based Ethertronics Inc., enabling innovative antenna and RF solutions to deliver the best connected experience, has launched Ether 1.3.1, a phone adaptive antenna solution. Ready for integration with smartphones or other classes of phones, the Ether 1.3.1 can realize design benefits such as 50 percent reduction in antenna volume, yet maintain compliant performance.

According to Laurent Desclos, president and CEO, Ether 1.3.1 allows an antenna system to dynamically tune itself for optimum performance.  Phone form factors are constantly changing throughout the design cycle.

“Current solutions, using passive antennas, require the antenna to be re-tuned with each change to the phone form factor, lengthening the time to market. Ether 1.3.1’s advanced active circuitry is able to adapt to changes in the form factor, reducing the need for lengthy antenna redesigns.”

In addition, Ether 1.3.1 can be designed to take up less volume than other antennas (up to a 50-percent reduction), providing more space for other components, and yet, still remain specification compliant.

Is this solution only suitable for smartphones then? Desclos said that Ether 1.3.1 is not limited to just smartphones.  It can be integrated into all tiers of devices such as feature phones and tablets supporting 2G, 3G, and 4G mobile device designs. Ether 1.3.1 is said to be ready for commercial deployment. Several design references have been accomplished to date. Products from OEMs will be announced in the future.

It is said that Ether 1.3.1 allows more freedom in antenna structure design. Elaborating, Desclos said: “Ether 1.3.1 allows more freedom in antenna structure design in a few core areas: size, placement and ability to meet performance specifications. Through the use of active impedance matching techniques, smaller volume antennas can be achieved.”

This is especially important as phone form factors shrink, while more components are added to phones for increased functionality (cameras, GPS, etc.). Ether 1.3.1 can additionally be used to achieve compliance as the antenna system can be dynamically tuned for known challenge areas in specification compliance.

Finally, how can the Ether 1.3.1 solution be tuned for tougher challenges by toning down the antenna size?

Typically, when the antenna’s size is decreased, performance suffers since there is less volume area to cover the required bandwidth. The beauty of active impedance matching is that the technique allows for the antenna volume to be reduced by as much as 50 percent and still maintain compliant performance. As a result, active impedance matching allows for a wide range of designs, since the technique is applicable to a broad range of form factors.
