1. A multiprotocol modular communication system, comprising:
a main circuit (1), provided with an antenna connector (5) for enabling connection of an antenna (4);
two or more connectors (2, 2a, 2n), provided with a first pin (10) and a second pin (11) connectable to one another, wherein the first pin (10) of a first connector (2) is connected to the antenna connector (5) by means of a track (6);
one or more communication boards (3), each operating with a determined communication protocol, each of which is insertable in a respective connector (2, 2a, 2n), wherein each communication board (3), if inserted in a connector (2, 2a, 2n), connects the first pin (10) and the second pin (11) of the connector;
characterised in that: the second pin (11) of each connector (2, 2a, 2n) is connected to the first pin (10) of a successive connector by means of a track (6) provided with a band-pass filter (7, 8); each band-pass filter (7, 8) has an impedance which is such as to block the frequencies used by the communication board (3) inserted in the preceding connector (2, 2a, 2n).
