The next generation wireless systems will be coming in scene soon. 5G is expected to reach markets by 2020 to monitor increasing demands for performance and data. A single obstacle in this path is that the technology world is yet to be prepared for this new technology. However, the good news is that enough research is underway for this purpose. A team of researchers in Aalto University of Finland is studying a completely new antenna design technology that will help in realizing level performance of 5G.
The present day mobile antennas are too stressed these days. They are being subjected to more and more stressed standards for better performance as the communication technology is evolving. Next, the makers expect these to cover larger grounds since different frequencies are used in different countries. Also, there is very restricted space available for present day phones. The engineers working on this have found a new technology for frequency reconfigurable antennas that can always help in configuring antennas with customizable capacitor matching networks that exists already. The main thing is that design of these antenna keeps away the requirement for space-grabbing analog components.
The method includes multiple antenna elements along with number of transceivers. When these antennas are kept close to each other you can always take benefit of mutual coupling. With the help of digital techniques, these engineers were able to customize the the transmit signal amplitude to every antenna in a manner that can build destructive interference for reflected waves. Researcher Jari-Matti Hannula says, “Traditionally one antenna works with either one or a few different frequencies. Now we can take advantage of advanced digital electronics and combine several small antenna elements to work together as one antenna that can be made to operate digitally with any frequency. In this way, many smartphone applications like GPS, Bluetooth and Wi-Fi will no longer need their own antennas. Instead, all of the phone’s data transfer can take place through one digitally controlled antenna. This in turn makes phone design easier and enables a larger screen size relative to phone size as the antenna does not require so much space. ”
