The invention provides a loop antenna comprising a feeder and an antenna body. The feeder comprises an anode and a cathode. The antenna body comprises a plurality of antenna units in a loop structure. The antenna units are symmetrically distributed around the feeder. The antenna units are connected with the anode and the cathode respectively. The loop antenna has the advantages that the frequency characteristics and directional characteristics of small-loop antenna are inherited, the antenna units are arranged on a solid face according to angles, and impedance is changed and reduced by array characteristics, thus directionality, impedance and gaining of the small-loop antenna are improved, low impedance and guaranteed directionality are comprehensively achieved, the gaining rarely greatly decreases, the impedance problem of the small-loop antenna is solved, and efficiency is remarkably improved.
