Remarks for integration of the receiver antenna
Please pay due attention to the design of the antenna ground plane based on the general design theory.
Locate the antenna in a place where there are no objects between TX and RX and that is visible from
the transmitter antenna. If a PCB pattern line is used for connection between the antenna terminal and
the antenna you choose, please secure the following pattern width.
PCB thickness (mm)
0.8 1 1.2 1.6
Pattern width (mm)
1.3 1.4 1.7 2.7
(The example above shows a case where a G10 double-sided PCB is used.)
