A wireless explosion-proof apparatus for wireless communication comprising: an antenna; an explosion-proof chamber comprising a casing; a communication module disposed in the explosion-proof chamber, the communication module configured to transmit and receive a wireless signal through the antenna; a connector portion having a central conductor, having one end connected to the communication module through a connection line and the other end, to which the antenna is electrically connected, exposed to the outside of the explosion-proof chamber; and a short stub module disposed in the explosion-proof chamber and disposed on the connection line, the short stub module being grounded to the casing and configured to secure electric conduction between the one end of the central conductor and ground so as to keep potential of the central conductor at a certain potential, wherein: the short stub module includes a distributed constant circuit the antenna is disposed outside the explosion-proof chamber. the short stub module is formed to correspond to a plurality of bands, the short stub module having a first connection line pattern in which a high-frequency signal is inputted from one end and outputted from the other end in a horizontal direction, and a second connection line pattern one end of which is connected to a central portion of a lower side of the first connection line pattern at right angles and the other end of which is DC-connected to the ground through at least one of crank-like patterns connected in series. an antenna; an explosion-proof chamber comprising a casing; a communication module disposed in the explosion-proof chamber, the communication module configured to transmit and receive a wireless signal through the antenna; a connector portion having a central conductor, having one end connected to the communication module through a connection line and the other end, to which the antenna is electrically connected, exposed to the outside of the explosion-proof chamber; and a short stub module disposed in the explosion-proof chamber and disposed on the connection line, the short stub module being grounded to the casing and configured to secure electric conduction between the one end of the central conductor and ground so as to keep potential of the central conductor at a certain potential, wherein: the short stub module includes a distributed constant circuit the antenna is disposed outside the explosion-proof chamber. the short stub module is formed to correspond to a plurality of bands, the short stub module having a first connection line pattern in which a high-frequency signal is inputted from one end and outputted from the other end in a horizontal direction, and a second connection line pattern one end of which is connected to a central portion of a lower side of the first connection line pattern at right angles and the other end of which is DC-connected to the ground through at least one of crank-like patterns connected in series. the short stub module includes a distributed constant circuit the antenna is disposed outside the explosion-proof chamber. the short stub module is formed to correspond to a plurality of bands, the short stub module having a first connection line pattern in which a high-frequency signal is inputted from one end and outputted from the other end in a horizontal direction, and a second connection line pattern one end of which is connected to a central portion of a lower side of the first connection line pattern at right angles and the other end of which is DC-connected to the ground through at least one of crank-like patterns connected in series.
