Note that the above antenna performance is measured with just the antenna mounted on a
reference PCB to similar a free-space condition. When implement into the system, the frequency
resonant might be off-tune due to the loading of surrounding components especially metal plane.
This off-tune can be compensated through matching. Although module manufacturers specify a
peak gain limit, it is based on free-space conditions. The peak gain will be degraded by 1 to 2dBi
in the actual implementation as the radiation pattern will change due to the surround components.
As such, during selection of antenna, you can select one with high peak gain to compensate for the
loss. Molex can offer assistant to choose the best location and best tuning in-order to meet this
peak gain requirement.

7.0 RF PERFORMANCE AS A FUNCTION OF IMPLEMENTATION
All measurements in this document are done on a reference PCB.
7.1 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH
PARALLEL PLANE GROUND FOR CONFIGURE 1 AND CONFIGURE 2
Four locations with parallel plane ground have been evaluated and the location presentation is
shown in figure 7.1. The plane ground size is 60mm*30mm and we move the plane ground to four
locations for each test.
The antenna performance is better with larger distance between antenna and parallel plane ground.
The minimum distance between antenna and plane ground is recommended to be 10mm to
achieve acceptable RF performance for configure 1.
The minimum distance between antenna and plane ground is recommended to be 5mm to achieve
acceptable RF performance for configure 2.
FIGURE 7.1 FOUR LOCATIONS WITH PARALLEL PLANE GROUND (USING CONFIG1 FOR
ILLUSTRATION)
Ground Size: 60mm*30mm;
Location D1: Distance between antenna and plane ground is about 5mm;
Location D2: Distance between antenna and plane ground is about 10mm;
Location D3: Distance between antenna and plane ground is about 15mm;

7.2 ANTENNA RF PERFORMANCE AS A FUNCTION OF DIFFERENT LOCATIONS WITH
VERTICAL PLANE GROUND FOR CONFIGURE 1 AND CONFIGURE 2
Four locations with vertical plane ground have been evaluated and the location presentation is
shown in figure 7.2. The plane ground size is 60*30mm and we move the plane ground to four
locations for each test.
The distance between antenna and vertical plane ground affect the antenna performance slightly.
The minimum distance between antenna and plane ground is recommended to be 10mm to
achieve acceptable RF performance for configure 1.
The minimum distance between antenna and plane ground is recommended to be 5mm to achieve
acceptable RF performance for configure 2.
FIGURE 7.2 FOUR LOCATIONS WITH VERTICAL PLANE GROUND (USING CONFIG1 FOR

Ground Size: 60mm*30mm;

7.3 ANTENNA RF PERFORMANCE AS A FUNCTION OF LOCATIONS ON REFERENCE PCB
FOR CONFIGURE 1 AND CONFIGURE 2
Two locations have been evaluated RF performance and these locations are shown in figure 7.3.
Figure 7.3.1, figure 7.3.2, figure 7.3.3 and figure 7.3.4 comparatively present the return loss and
efficiency at two locations.
The performance of location 1 is much better than location 2. So the location 1 (upper center location)
is the recommended location for this antenna.

7.4 RF PERFORMANCE AS A FUNCTION ON DIFFERENT SIZE GROUD FOR CAONFIGURE 1
AND CONFIGURE 2
Three kinds of ground plane size were used for this study, which were 80mm*60mm, 60mm*40mm,
and 40mm*20mm.
From the test result we can see the antenna performance is the best using reference PCB size
