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
• 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

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.

Figure 3: D-cover assembly
• If the internal antenna is missing, install one. If the radiator looks obviously
damaged, then replace the internal antenna.
• If the whip is missing, then remove the internal antenna, install a whip, and
reinstall the internal antenna.
Internal Antenna
The internal antenna has a metal sheet (main antenna radiator) and a metal strip
(GPS antenna radiator) attached to a plastic carrier. An IHF mini speaker is integrated
inside the plastic.

Damaged RF Feed or Ground Pins
The main antenna and the GPS antenna have pins (spring clips) that should properly
touch the PWB. If the RF feed pin of the main antenna does not touch the PWB, the
antenna gain will degrade by more than 25 dB and the GPS antenna will be detuned. If
the ground pin of the main antenna does not touch the PWB, the antenna gain may
degrade about 5 to 10 dB and the GPS antenna will be detuned.
If the RF feed pin of the GPS antenna does not touch the PWB, then the GPS antenna
gain will degrade by more than 20 dB. If the ground pin of the GPS antenna does not
touch the PWB, the GPS antenna gain may degrade more than 5 dB.
Figure 5: Back view of the internal antenna
• If either the RF feed pin or ground pin are broken or bent such that either pin will
not touch the PWB, then replace the internal antenna.
• If the springs for the RF or ground pin appear damaged, then replace the internal
antenna.
Damaged IHF Speaker Pogo Pins
In Figure 5, the two pogo pins on the back of the internal antenna should properly touch
the PWB. If not, the PCS gain of the internal antenna could degrade about 2 dB and
there will be no audio from the speaker.
Wrong Internal Antenna Installed
The internal antenna is mechanically similar to the internal antenna for the 2285, 2270,
2275 (RH-3 series) and the 2280 (RH-17) phones. There are three important differences
between the internal antennas:
• Only the internal antenna for the 6015/6015i/6016i/6019i, and 6012 phones
includes an IHF speaker.
• The slot pattern is very different among all three antennas.
• The radiators for the 2285, 2270, 2275 (RH-3 series) and the 2280 (RH-17)
phones are marked with an “F” and an “H” respectively.

Figure 6: Top view of the 6015/6015i/6016i/6019i, and 6012 internal antenna
Figure 7 shows the antennas for the 2285, 2270, 2275 and the 2280 phones. Ensure that
these antennas are not installed.
Figure 7: Top views of internal antenna for the 2285, 2270, 2275 (left)
and the 2280 (right) phones
Installing the 2285, 2270, 2275 or 2280 antenna in the 6015/6015i/6016i/6019i, and
6012 phones is not compliant with Nokia’s FCC submission because the 2285, 2270,
2275 (RH-3 series) antenna uses a single-band antenna (no PCS) and it does not have a
GPS antenna. The 2280 (RH-17) antenna is not tuned correctly for the 6015/6015i/
6016i/6019i, and 6012 mechanics.
• If the wrong antenna is installed, install the correct one.
• If the slot in the radiator has a significantly different shape, then install the
correct internal antenna. Be aware that the shape of the slot can vary slightly.
The length of the horizontal slot and the opening of the vertical slot can vary by
few millimeters because the antennas are tuned for each batch of plastic frames.
• If there is any other obvious damage to the radiator (dents, corrosion), replace
the antenna.
• If the pin gets stuck or has excessive friction in the plastic tube/guiding feature,
then the spring will not work properly, and you should replace the antenna.

Obstructed IHF Speaker, RF Feed, and Ground Pads
Figure 8: PWB layout of IHF speaker, RF feed, and ground pads, as well as the bottom antenna clip
If any of the RF feed or ground pins are obstructed, removed, or covered, then the RF pin
will not touch the PWB and the antenna performance will degrade. If any of the IHF
speaker pads are obstructed, removed, or covered, the speaker’s pogo pin will not touch
the PWB and the antenna performance at PCS could degrade. See the "Damaged IHF
Speaker Pogo Pins" section for antenna performance degradation if any pogo pin does
not touch the PWB.
• If corrosion is present or the pad is missing, then you should replace the PWB and
the phone.
• If a pad is obstructed or covered, then clear and/or clean the pad.

Broken or Missing Bottom Antenna Clip
If the bottom antenna clip does not contact the whip stopper when the whip is fully
retracted, the internal antenna gain will degrade by about 4-5dB at Cell band and
3-10dB at PCS band.
Figure 9: Bottom antenna clip
• If the antenna clip is installed backwards, is damaged, or is missing, then install a
new bottom antenna clip in the correct position.
Obstructed Whip Stopper
If the whip stopper does not properly contact the bottom antenna clip, then the internal
antenna gain will degrade by about 4-5dB at Cell band and 3-10dB at PCS band when
the whip is retracted.
