Flavus GSM Snap-In Antenna
Part No. B5812-xx
10-2 Matching circuit
The antenna requires a matching circuit that must be optimized for each customer’s product.
The matching circuit will require up to three components and the following pad layout should be
designed into the device so the correct circuit can be installed:
In addition to the matching circuit, a separate DC blocking capacitor will also be required
between the radio and the antenna matching circuit.
Dimensions “W” and “T” will depend on the material and thickness of the PCB and must be
calculated to give a transmission line with a 50Ω characteristic impedance.
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 a matching service on
request. Contact
