4.3 Antenna Design Guide
SIM5320 provides RF antenna interface. Customer’s antenna should be located in the host board and
connected to module’s antenna pad 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 pad and antenna should meet the following requirements:
● GSM900/GSM850<0.5dB
● DCS1800/PCS1900 <0.9dB
● WCDMA 2100/1900<0.9dB
● WCDMA 900/850<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.
