Researchers at Aalto University in Finland have developed a method that enables antennas to make the shift from the analog to the digital world. They say the antenna makes it possible to reach the data transfer speed set as the goal for the next generation of phones, which is 100 to 1,000 times faster than that of current phones.
In addition, the researchers say battery life will be improved thanks to the greater efficiency of the new method.
They also note the new method provides greater bandwidth, which leads to a higher data transfer speed and improved efficiency.
Aalto professor Ville Viikari says the new method could revolutionize the fifth generation of mobile phones. "The next step in the development process is underway with the commencement of tests in cooperation with Huawei using fifth-generation mobile phone devices," he notes. "We are also developing together with Aalto University researchers digital electronic systems for controlling the antennas."
The new antennas also may dispose of the analog components that traditional antennas use to tune into the desired frequency, which facilitates antenna design and enables the creation of more compact antennas with better radiation efficiency.
