Introduction
The mobile terminal includes an internal antenna. This antenna arrangement is used for
PCS frequency bands. The internal antenna assembly adopts Monopole Antenna
structure used for the PCS engine.
Visual Quality Requirements
Below are the minimum acceptable visual quality requirements of the internal antenna
assembly:
zWear gloves to assemble the antenna. Don’t touch the antenna radiator with bare
hands.
zNo visual cracks or mechanical defects.
zNo oil, dirt, or particles are present on the parts.
zRadiator must be aligned with the plastic housing.
zRadiator must be flat with no warping.
zThe length of all pins must be identical and the pins align.
Failures and Corrective Measures
The internal antenna is assembled into the Back Cover Assembly as shown in Figure 1.
If no internal antenna is installed, the antenna gain is degraded by more than 20 dB.
zIf the internal antenna is missing, install antenna-asm Module.
zIf the radiator looks damaged, replace it with a new antenna–asm Module.
