(WCDMA B1, WCDMA B2, WCDMA B4, and WCDMA B5,WCDMA B8) and LTE bands(LTE B2,LTE B3,
LTE B4, LTE B5,LTE B7 ,LTE B17 and LTE B20), and has 2 connection. The antenna radiator is deposited
on a plastic carrier with LDS technology and connected to the board through C-clips. A diplexer is used for
dividing HB and LB due to antenna structure.
The diversity antenna covers WCDMA bands (WCDMA B2 and WCDMA B5) and LTE bands (LTE B2, LTE
B3, LTE B4, LTE B5, LTE B7, LTE B17, and LTE B20). The antenna has one feed contact and one ground
