Antenna Description and Troubleshooting

Introduction

The mobile terminal includes an internal antenna. This antenna arrangement is used for Cellular frequency
bands. The internal antenna assembly adopts Monopole Antenna structure used for the cellular engine.

Visual quality requirements

Below are the minimum acceptable visual quality requirements of the internal antenna assembly:

Wear gloves to assemble the antenna. Don’t touch the antenna radiator with bare hands.

No visual cracks or mechanical defects.

No oil, dirt or particles attached on the parts.

Radiator must be flat without warping and aligned with the plastic housing.

The length of all pins must be identical and the pins align.

Failures and corrective measures

The two antennas are assembled into B Cover as shown in Figure 1. If no internal antenna is installed, the

antenna gain is degraded by more than 20 dB.

If the internal antenna is missing, install antenna-asm Module.

If the radiator is damaged, replace it with a new antenna-asm Module.
