FXP72070053A Datasheet, PDF (12/13 Pages) List of Unclassifed Manufacturers – FXP72 Freedom 2.4GHz Series Ground Coupled Antenna

The size and shape of the ground plane can change. The only restrictions to get maximum
performance are that the antenna must be allocated along the shortest edge of the device
board, and the ground plane on that edge must have a flat shape horizontally, in order
words the ground plane can not come around of the antenna sides on that section. The
next figure 13 shows a non desired ground plane environment.
Figure 13. Not recommend ground plane.
The size of the ground plane used on the testing had a dimension of 40X60 mm, see next
figure 14. The antenna was placed in the center of one shortest edge. The antenna was in
between the ABS plastic and ground plane, having a clearance of 8 mm. The Antenna was
tested into the Satimo system chamber and with a network analyzer. The antenna was
also tested on in free space, just the antenna stuck out on the ABS plastic of 1.5 mm of
thickness.
