New innovations welcomes smartphones users who are struggling with their poor reception, slow downloads, and also with poor battery life. Radio Science and Engineering Department researches in Finland’s Aalto University developed antenna design that improves reception, power consumption and data-transfer speed
Recently, smartphones are provided with multiple antennas that work with one or more frequencies and are dedicated to specific smartphone applications, such as mobile reception, GPS, and Bluetooth.
This new method changes the approach by combining several small antenna elements together as a single aerial antenna that controls digitally to operate at any given frequency.
While at instance we have around seven antennas in a phone, with which we can reduce the amount to maybe two, because we’re can adjust to any frequency we want. For multiple frequencies one compact antenna is used, it clears space for the larger touchscreens, thanks to smaller bezels, without the need for sacrificing the phone’s performance.
Antennas are left with less space in recent phones, although they are needed more as they have to work with Wi-Fi, Bluetooth. Antenna technologies allows for obtaining a broad frequency range or high efficiency, but not for both at the same time.
The frequency range used by smartphones is increasing constantly, the radiation efficiency has fallen and leads to shorter transmission ranges.
With the new digital method to give the antenna greater bandwidth, results in better radiation efficiency and the 100 to 1,000 times faster data transfer speeds set and act as an objective for the next-generation.
This improves battery life, but there are no estimates of how much yet. The antenna definitely works, but it needs an integrated chip attached to it. The best way to execute a radio in this kind of an antenna is through the current radio chips which has been designed for standard antennas.
