PURPOSE: A slot antenna is provided to gain a high directionality and an omnidirectional radiation pattern by forming a plurality of slots on a ground plane of a strip transmission line. CONSTITUTION: A slot antenna includes a dielectric substrate(110), a ground plane and a pair of stubs(130). Micro strip transmission lines(160,170) and a strip transmit line(150) are formed on the dielectric substrate. The ground plane is respectively located on upper side and lower side of the dielectric substrate. The ground plane is connected through a plurality of ground vias(122,142) each other. A pair of stubs is arranged on the dielectric substrate as the fixed interval. An interval and a length of a pair of stubs are in inverse to a frequency.
