Abstract
To provide a dual polarized antenna capable of reducing correlation between antenna elements.A dual polarized antenna is constituted by a vertically polarized antenna and a horizontally polarized antenna formed on a printed circuit board and radiates two kinds of polarized waves. The vertically polarized antenna has a configuration in which: a first microstripline is extended along the longitudinal direction of the printed circuit board from the lower portion of the printed circuit board; a first conductive radiating element is disposed at one end of the first microstripline; a phase delay circuit is serially connected to the first conductive radiating element; a second conductive radiating element is added to one end of the phase delay circuit; and a third conductive radiating element is added to a ground conductor which is disposed on the rear side of the surface of the printed circuit board on which the first conductive radiating element and first microstripline are connected at a corresponding portion thereof.
