GSM /UMTS/LTE Antenna Design Guide
Users should connect antennas to MODULE’s antenna pads through micro-strip line or other types
of RF trace and the trace impedance must be controlled in 50Ω. SIMCom recommends that the
total insertion loss between the antenna pads and antennas should meet the following requirements:
Table 29: Trace loss
Frequency
Loss
700MHz-960MHz
<0.5dB
1710MHz-2170MHz
<0.9dB
2300MHz-2650MHz
<1.2dB
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.
