PURPOSE: A micro-strip patch antenna is provided to prevent damage to a conversion structure by supplying power from a wave guide pipe to an antenna. CONSTITUTION: A wave guide pipe is connected to a first area (135) of a circuit board (120). Ground is arranged at a lower surface of the circuit board. The ground eliminates the conductor of the first area. An antenna unit (110) is arranged on the circuit board. The antenna unit transmits an electronic wave as a signal with supplied power. The antenna unit comprises a first power supply unit (112) of a metal board arranged on the first area; a first radiation unit (114) connected through a transmission line and the power supply unit; and a second radiation unit (116) corresponding to the first radiation unit. |
