Antenna overview
The phone has five different antenna assemblies:
•
The main antenna which is placed at the bottom of the phone
•
A MIMO/diversity antenna which is placed on the side of the phone
•
A GPS/LTE7 MIMO antenna which is placed at the top of the phone
•
WLAN/BT antenna which is placed at the top of the phone
•
NFC antenna which is placed on the battery cover
The main antenna covers four GSM bands (GSM850, GSM900, GSM1800, and GSM1900), four WCDMA bands
(WCDMA 8, WCDMA 5, WCDMA 2, and WCDMA 1), and four LTE bands (LTE 1, 3, 8 and LTE 20), and has separate
antenna feeds for low and high band. The antenna radiators are deposited on a plastic carrier with LDS
technology and connected to the board through standard C-clips. The antenna module also functions as an
acoustic chamber that has a Donau IHF speaker.
