9. Electrical Interface
9.1 Host Interface
The host PCB requires the mating connector which is IPEX 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 50Ω impedance.
9.2 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 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 like
with PCB mounted antennas. However placement still needs to follow some basic
rules, as any antenna is sensitive to its environment.
Using six spatial directions shown below as a guide. The antenna FPC section
should try to maintain a minimum of three directions free from obstructions to be able
to operate effectively. The other directions will have obstacles in their paths, these
directions still require a minimum clearance. These minimum clearances are further
defined in this section. The plastic case is not included in this, only metal
objects/components that will obstruct or come in close proximity to the antenna.
Six spatial directions relative to FPC

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. Below shows the
minimum value of (d) for each. Other obstructions may increase this dimension.
1) Vertical mounted
1) Co-planar to PCB
2) Planar to PCB (Same plane)

11. Hazardous Material Regulation Conformance
The antenna has been tested to conform to RoHS requirements. A certificate of
conformance is available from Antenova M2M’s website.
12. Packaging
The antennas are stored in individual plastic (PE) bags. Then stored within a second
bag of 10pcs.
Single antenna per bag 10 units per second bag (Labelled)
12.1 Optimal Storage Conditions
Temperature
-10ºC to 40ºC
Humidity
Less than 75% RH
Shelf life
18 Months
Storage place
Away from corrosive gas and direct sunlight
Packaging
Antennas should be stored in unopened sealed manufacturer’s
plastic packaging.
The shelf life of the antenna is 18m, provided the bag of 10 pieces remains factory sealed.
