Nokia Customer Care Troubleshooting — Antenna
Introduction
The 6015/6015i/6016i/6019i, and 6012 incorporate a dual-band, internal/whip antenna
combination. This antenna arrangement is used for both AMPS/CELL and PCS frequency
bands. The whip is capacitively coupled to the internal antenna when extended. The
internal antenna assembly consists of a Planar Inverted-F Antenna (PIFA) used for the
cellular engine and an Inverted-F antenna (IFA) used for the GPS engine, which is placed
on the side of internal antenna body.
The GPS antenna is only active on models that support the GPS engine (i.e., 6015/6015i/
6016i/6019i).

Visual Quality Requirements
Whip Antenna
Check the following minimum visual quality requirements of the whip assembly:
• No physical cracks, bends, or mechanical defects
• No oil, corrosion, dirt, or particles
• Whip can be fully retracted and/or stowed without interference
• When fully retracted, antenna bottom stopper locks into antenna plug
Frequency
(MHz)
Active GPS
• Antenna wire and/or cap is not missing, cracked, or bent
• Color of antenna (cap, plug, wire and straw) is a very dark grey
• Wire straw is present with no visible defects

Internal Antenna
Following are the minimum acceptable visual quality requirements of the internal
antenna assembly:
• Gloves must be used when handling antennas. Do not touch the antenna radiator
with bare hands.
• No visual cracks or mechanical defects.
• No oil, dirt, or particles are present on the parts.
• Radiator must be aligned with the plastic housing.
• GPS antenna contacts must be inside the plastic housing.
• Radiator must be flat with no warping.
• All pins must be at the same level.

Failures and Corrective Measures
Figure 2: Back view with the whip retracted (left) and whip extended (right)
Note in Figure 2 that when the whip is properly installed, the cap clicks into the D-cover
when the whip is fully retracted.
Antenna Position into D-cover
The internal antenna and whip are assembled into the D-cover as shown in Figure 3. The
whip must be inserted prior to inserting the internal antenna.
If no internal antenna is installed, the antenna gain will be degraded by more than
25 dB.
