3.4 eLTE-IoT Module eM300-8a Antenna Design Guide
Users should connect antennas to eM300-8a’s antenna pads through micro-strip line or other types of RF
trace and the trace impedance must be controlled in 50Ω.Reference Design recommends that the total
insert on loss between the antenna pads and antennas should meet the following requirements:
Trace loss
Frequency
loss
902MHz-928MHz
＜0.5dB
To facilitate the antenna tuning and certification test ,a RF connector and an antenna matching circuit
should be added.The following figure is the recommended circuit.

In figure ,the componenets R5,C13,C14and C50 or C51 are used for antenna matching.
The value of componnets can only be achieved after the antenna tuning and usually provided by antenna
vendor.By default,the R5 are 0Ω resistors,and the C13,C14 are 4.7pF，and they are reserved for tuning
The RF test connector is used for the conducted RF performance test,and should be placed as close as to
the module’s RF_ANT pin.The traces impedance between eM300-8a and antenna must be controlled in
50Ω。

not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation If
this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved by the party responsible for compliance could
void the user‘s authority to operate the equipment.
RF Exposure Information
This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order
to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the
antenna shall not be less than 20cm (8 inches) during normal operation.
