9. Electrical
Interface
9.1 Host Interface
The host PCB requires the mating connector which is the I-PEX MHF (UFL)
receptacle. The location should be close to the chip/modules pin for the RF. Any
feed from this receptacle should be maintained at 50
Ω
impedance.
9.2 Transmission Line
All transmission lines should be designed to have a characteristic impe
dance 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 feed.
A DC blocking capacitor should be placed in line to protect the RF front end.
10. Mechanical
Fixing
The antenna uses 3M 468MP adhesive on the reverse side of the FPC. The antenna
has an easy access split line to peel off to reveal the adhesive side. It is designed for
a one time fix to a clean smooth surface.

10.0 Antenna Integration Guide
10.1 Placement
For placing the FPC antenna within a device, the host PCB size is not a factor as
with PCB mounted antennas. However placement still needs to follow some basic
rules, as any antenna is sensitive to its environment.
Use the six spatial directions shown below as a guide.
The antenna FPC section
should ideally maintain a minimum of three directions free from obstructions to be
able to operate effectively. The other directions will have obstacles in their path –
these directions still require a minimum clearance.

10.2 Orientation of FPC
The orientation of the FPC with respect to the host PCB should be defined
depending on the unit. The proximity of the GND will have an influence on the
antenna so the PCB location relative to the antenna should be considered.
The FPC will normally be placed in one of the three following options for orientation.
In each option a distance (d) is the critical dimension to consider. See the minimum
value of (d) for each, below. Other obstructions may increase this dimension.

10.3 Device Integration Example
An example of integration within a drone is shown below. The device contains the
major components along with the device outer case. The FPC is shown adhered to
the inside of the device
’s
plastic housing. The length of the cable should be chosen
to be sufficient to allow ease of assembly when produced (SRFG017-100 in
example).
The FPC was placed vertically relative to the PCB. The FPC is kept at maximised
height above the PCB to ensure it is above the minimum
clearance of ≥
2mm. This
example shows the FPC 5mm above the PCB. For this type of device it is advisable
to keep the antenna away from the electric motor cables and motors themselves that
may interfere.
For vertical placement
relative to PCB d=15mm
(min
≥2mm)
