4.2 LTE Antenna Design Guide

Users should connect antennas to Module’s antenna pads through the micro-strip line or other types

of RF trace. The trace impedance must be controlled in 50Ω. SIMCom recommends that the total

insertion loss between Module and antenna should meet the following requirements:

Table 24: 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.

SIM7500V provides LTE antenna named MAIN_ANT, customer could use 50Ω microstrip

line or stripline antenna connect to the module.
