FXP72070053A Datasheet, PDF (11/13 Pages) List of Unclassifed Manufacturers – FXP72 Freedom 2.4GHz Series Ground Coupled Antenna

5. Mounting Guidelines
This versatile antenna design is suitable for cases where there is not enough space for a
thicker antenna. FXP72 can be right next to the device main board. This antenna uses the
device main board as a ground plane through a capacitive coupling effect and keeping
antenna characteristics.
The only restriction for this design is the radiated elements of the antenna must be free of
metal. In the next figure 12 is shown the minimum clearance necessary for the antenna
and on Figure 13 the non-desired main board shape on the antenna section. The size of
the ground plane used on the testing is 40X60 mm and was allocated as in figure 12.
