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.
