Calvus GSM SMD Antenna
Part No. A10340
Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a co-
planar transmission line can easily be designed using any of the commercial software
packages for transmission line design. For the chosen PCB thickness, copper thickness and
substrate dielectric constant, the program will calculate the appropriate transmission line width
and gaps on either side of the track so the characteristic impedance of the co-planar
transmission line is 50Ω.
11-2 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 depending on the impedance of the
antenna when situated in the device, and pads have been designed for 0603 components for
best results. In addition to the matching circuit, a separate DC blocking capacitor will also be
required between the radio and the antenna matching circuit.
The following pad layout should be designed into the device so the correct circuit can be
installed:
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.
