Product Specification AE020157-O

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 M2M offers this service on request.

10-3 Antenna placement

Antenova M2M 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.
