PURPOSE: A double polarization array antenna with an air-strip power distributor is provided to reduce a loss and enhance productivity by forming the power distributor using an air-strip having a great allowable power capacitance and designing the distributor with a serial circuit format serially connected to respective radiation elements. CONSTITUTION: A plurality of radiation elements(1,2,3,4) of flat plate shape are positioned to be opposite from each other and implement the double polarization. A reflecting plate(15) reflects signals radiated toward the rear parts of the radiation elements(1,2,3,4). A plurality of radiation element supporters are installed so that the plurality of radiation elements(1,2,3,4) can be fixed to be spaced apart from the reflecting plate(15). An air-strip power distributor(13) consists of an air-strip to assign input signal power to the plurality of radiation elements(1,2,3,4) and implement the orthogonal feeding. A cover protects the antenna against external environment.
