摘要：An antenna apparatus utilizing an aperture of transmission line, which isconnected to a first transmission line having a predetermined characteristic impedance,
includes a tapered line portion, and an aperture portion. The tapered line portion isconnected to one end of the transmission line, and the tapered line portion includes asecond transmission line including a pair of line conductors. The tapered line portionkeeps a predetermined characteristic impedance constant and expands at least one of awidth of the transmission line and an interval in a tapered shape at a predeterminedtaper angle. The aperture portion has a radiation aperture connected to one end of thetapered line portion. A size of one side of the aperture end plane of the aperture portionis set to be equal to or higher than a quarter wavelength of the minimum operatingfrequency of the antenna apparatus.
