1. A microwave-doppler detecting module for radiating an electromagnetic wave for detecting an object activity in a directional space, comprising:
a first radiating source pole configured to be a conductive wire having a first feed end and a second radiating source pole configured to be a conductive wire having a second feed end, wherein said first radiating source pole, from said first feed end along said first radiating source pole, is correspondingly coupled with corresponding positions of said second radiating source pole, from said second feed end along said second radiating source pole, to form a radiation space which is a coverage area of the electromagnetic wave radiated by said microwave-doppler detecting module and is formed protruding in a radial direction of a connection of said first feed end and said second feed end to avoid a detection dead zone in said radial direction, wherein said first radiating source pole and said second radiating source pole are adapted for being fed by an excitation signal feed source at said first feed end and said second feed end respectively, wherein said first radiating source pole is configured to satisfy to have a wire length greater than or equal to λ/16 from said first feed end and said second radiating source pole is configured to satisfy to have a wire length greater than or equal to λ/16 from said second feed end; and
an electromagnetic reflecting surface, wherein said first radiating source pole and said second radiating source pole are arranged spacingly to said electromagnetic reflecting surface in the directional space corresponding to said electromagnetic reflecting surface such that said microwave-doppler detecting module is adapted for detecting the object activity in the directional space, wherein a reflection of a radiation of the electromagnetic wave from said first radiating source pole and said second radiation source pole toward said electromagnetic reflecting surface at a radiation direction corresponding to the radial direction of the connection of said first feed end and said second feed end to construct a sensing direction of said microwave-doppler detecting module from said electromagnetic reflecting surface toward said first radiating source pole and said second radiating source pole to enhance the radiation of the electromagnetic wave in the sensing direction to enhance a directional range of said microwave-doppler detecting module.
