ABSTRACT:
An antenna apparatus utilizing an aperture of transmission line, which is connected to a first transmission line having a predetermined characteristic impedance, includes a tapered line portion, and an aperture portion. The tapered line portion is connected to one end of the transmission line, and the tapered line portion includes a second transmission line including a pair of line conductors. The tapered line portion keeps a predetermined characteristic impedance constant and expands at least one of a width of the transmission line and an interval in a tapered shape at a predetermined taper angle. The aperture portion has a radiation aperture connected to one end of the tapered line portion. A size of one side of the aperture end plane of the aperture portion is set to be equal to or higher than a quarter wavelength of the minimum operating frequency of the antenna apparatus.
