Disclosed is a slot antenna. According to one aspect of the present invention, provided is the slot antenna comprising: a waveguide space which is defined inside a waveguide main body and is extended along a first direction; and discharge slot which is formed along a second direction which is intersect with the first direction from one side of the waveguide main body and is connected to the waveguide space. The discharge slot includes first and second side units located on both sides of the waveguide space by being formed longer than the width of the waveguide space. The depth of the first side unit is deeper than the depth of the second side unit. According to one aspect of the present invention, the slot antenna having a relatively simple structure is provided by using a new shaped slot. If the corresponding slot antenna is used, high leveled precision can be maintained and efforts and costs required for production can be reduced even if a signal of a very short wavelength is used. Moreover, the strength, phase, and matching of a signal can be tuned by using various methods in the provided slot antenna. |
