GSM or GPRS or 3G employ a wide range of frequencies ranging from 800MHz to 2100MHz but packaging restrictions and size allowances does not allow a big antenna to be packaged inside the module and hence we have to use the PCB antennas which are also known as microstrip antennas to connect to the network. They are usually printed on PCBs small enough to fit inside the module and connected to transmitter and receiver with thin wires. To transmit the radio waves current is supplied between the antenna and ground plane. It also comes with a standard coaxial 3DBI 15cm long IPEX connector to directly connect with the RF module that you have which require an external antenna to work. You can directly connect it to SIM800, SIM900, SIM908 GSM Modules.
