Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a
coplanar 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 coplanar
transmission line is 50 Ω.
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:
Antenna feed pad indicated. All other pads should be connected to ground.
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.

All transmission lines should be designed to have a characteristic impedance of 50 Ω
The length of the transmission lines should be kept to a minimum
Any other parts of the RF system like transceivers, power amplifiers, etc, should also be
designed to have an impedance of 50 Ω
