Antenna Design Guide

SIM5320AL 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.The maximum gain of the Main antenna gain should not exceed
1dBi considering the SAR radio. No antenna gain may be used that would exceed the 2W EIRP power
limit in 1900MHz band.The input impendence of the antenna should be 50Ω, and the VSWR should be
