Rufa 2.4 GHz SMD Antenna
Part No. A5839 / A5887
In addition to the matching circuit, a separate DC blocking capacitor will also be required
between the radio and the antenna matching circuit.
Note: The component values for the matching circuit will vary depending on the size of
the PCB and surrounding components. The impedance of the antenna should be measured
before selecting suitable matching components. Antenova offers this service on request.

10-3 Antenna placement
Antenova strongly recommends placing the antenna near the edge of the board. Maximum
antenna performance is achieved by placing the antenna towards one of the corners of the
PCB and with the feed point of the antenna as close to same corner of the PCB as possible.
Additional ground and components near the antenna should be at a distance of at least 2 mm.
Where possible the antenna should be clear of ground from both sides, although the antenna
can work well with a minimum clearance of D ≥ 2 mm as shown in the drawing above.
