11. Electrical Interface
11.1 Transmission Line
All transmission lines should be designed to have a characteristic impedance of 50Ω.
• 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.
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 co-
planar transmission is 50 Ω.
11.2 Matching Circuit
The antenna requires a matching circuit that must be optimized for each product. The
matching circuit will require up to six components, the following circuit should be designed
into the host PCB. Not all components may be required but should be included as a
precaution. The matching network must be placed close to the antenna feed to ensure it
is more effective in tuning the antenna.

The antenna should ideally be placed on the host PCB using one of the two configurations
below.
1) Horizontal placement
2) Vertical placement
Note: Vertical placement optimal minimum GND length required is ≥100mm

12.3 Diversity Placement
For a Diversity solution, use 2 x Integra on the same host PCB. For all configurations the
distance between them should be 20mm
Please note: It is still advisable to consult Antenova before building the PCB for additional
checking of the layout and device.

12.6 Component Distance Rule
While it is ideal to keep distance from metal objects and other PCB components, it is
possible to have components around the antenna. No set distance is set and varies
depending on the height of the component. So rather than setting a defined distance a
rule can be given. An 8° projection line can be drawn from the base of the antenna. This
can then be used to decide the distance a component can be.
The example below shows a USB connector placed using this rule. Once it is within
the 8° limit the distance is known.

13.0 Antenna Active Tuning for Smaller GND planes
For a host PCB with a length less than 75mm is it suggested to use an active tuning circuit
to overcome the BW reduction seen with smaller GND. This can be implemented on a
single antenna or diversity solution. An Antenova EVB kit is available with this circuit
(SR4L049-EVB-3).
The SR4L049-EVB-3 evaluation PCB uses a simple RF switching circuit to select
between two component values on the T1(Pin4). In this kit the RF switch used is a
Peregrine PE423422.
