Antenna Design Configuration
Receiver Module - Tips for antenna connection
1) The receiver module must be powered from a regulated voltage.
2) In proximity of the receiver module it is necessary to insert a ceramic decoupling capacitor (100nF).
3) The ground plane must be completely encircle the entire receiver in particular the area of the Antenna connection (we recommend a
minimum of 40-50mm radius).
4) The 50ohm connection should be as short as possible
5) For a pcb with 1.6mm thickness, the track “50ohm connection” must be 2.5mm, this track should be separated from the GND for 2mm.
6) On the opposite side of 50ohm connection should be a ground plane.
7) Keep the receiver module away from other components for more than 5mm.
8) Close to the 50ohm connectione there must be no component at least for 5mm.

Transmitter Module - Tips for antenna connection
1) The transmitter module must be powered from a low voltage source, safely protected against the short circuit.
2) In proximity of the transmitter module it is necessary to insert a ceramic decoupling capacitor.
3) The ground plane must be completely encircle the entire transmitter in particular the area of the Antenna connection (we recommend a
minimum of 40-50mm radius).
4) The 50ohm connection should be as short as possible.
5) For a pcb with 1.6mm thickness, the track “50ohm connection” must be 2.5mm, this track should be separated from the GND for 2mm.
