Note that the above antenna performance is measured with just the antenna mounted on a
PC/ABS block 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.
