The invention provides a radio wave receiving antenna, a receiving device, a radio wave perspective system and a detecting method for detecting a fully mechanized coal mining face of a mine through the radio wave perspective system. The radio wave receiving antenna comprises a plurality of signal receiving terminals which are used for being connected with a receiver. The signal receiving terminals are located in different directions to receive radio wave signals from different directions respectively and to convert the radio wave signals into electrical signals to transmit the electrical signals to the receiver. Due to the fact that the signal receiving terminals in the receiving antenna are located in the different directions to receive the radio wave signals from the different directions and to convert the radio wave signals into the electrical signals, the receiving capability for radio waves of the receiving antenna can be improved.
