You probably don't need to be very familiar with the problem that plagues the models Galaxy A5, Galaxy A3 and A7. Because of the all-aluminium, they have a problem with the signal strength, as metals do not transmit the signal as well as, for example, plastic materials. Samsung is aware of the problem and doesn't want it to happen again Galaxy S6. That is why he decided to switch to a completely new technology, which will allow him to achieve higher signal quality with premium materials, without having to compromise on the design of the device.
More precisely, he decided to use an FPCB antenna, which means the use of a flexible plate that can be placed in places where the mobile phone reaches the maximum signal range. In addition, it is possible to split its sections so that one is the mobile antenna, the second NFC, the third WiFi and so on. Up to now, mobile phone models from Samsung have used the LDS antenna, which stands for Laser Direct Structuring.
