The certified matching circuit as following:  5.1 GSM Antenna Interface  There is a GSM antenna pad named RF_ANT for SIM800H the connection of the antenna must be decoupled from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an inductor for ESD protection. The  external  antenna  must  be  matched  properly  to  achieve  best  performance,  so  the  matching  circuit  is necessary, the connection is recommended as following:   Figure1: GSM antenna matching circuit R101,C101,C102 are the matching circuit, the value should be defined by the antenna design. normally R101 is 0Ω, C101 和C102 are not SMD.
