As we approach the 5G era, mobile and portable applications of wireless technology are continuing to develop rapidly towards energy efficient handsets that can be connected to any network at any time at any place. This vision places stringent design requirements on the RF frontend and in particular the antenna design that needs not only to be small size and low cost but also it is now essential to address the need for wide, or multi-band operation, compliance with international safety guidelines on Specific Absorption Rate (SAR) and weak coupling of the antenna with the handset case in order to achieve the best impedance match in the presence of a human body.


Considering the state-of-the-art in the domain of balance antenna concept, the goal of VALUE project is to design, fabricate and test a novel family of compact and low-profile balanced antennas suitable for integration with mobile handsets.They will be designed for the latest mobile standards referred to as 4th generation or LTE, and operating within the range between 700 to 2600 MHz frequency bands with a workable bandwidth and acceptable power gain. This investigation also encompasses the impact on performance and specific absorption rate (SAR).
