A loop antenna to be conveniently manufactured is provided to control property accurately by using a stub and an element with a constant size. A loop antenna to be conveniently manufactured includes a radiation property control unit(200). The radiation property controlling unit(200) is installed at one side angle of a square radiation unit element(201) of a new radiator(110) to transmit an electric wave. A reflection property control unit(300) is installed at one side angle of a square reflection unit element(301) of the new radiator(110) to control electric wave property and gain. A waveguide property unit(350) induces the electric wave radiated from the radiation property control unit(200) and the reflection property control unit(300). An element folding unit(400) forms the square radiation unit element(201), the square reflection unit element(301), and a waveguide unit first element(351) close to an original form to improve the electric wave property. An element separating unit(500) is installed at each opposite angle of the radiation property control unit(200), the reflection property control unit(300), and the waveguide property unit(350) to improve the radiation property of the antenna.
