1. An antenna apparatus, comprising:
a ground substrate;
a feeding point provided on the ground substrate;
a first conductor device of which one end is electrically connected to the feeding point and which has a plate shape being parallel to the ground substrate;
a second conductor device which is arranged between the first conductor device and the ground substrate, of which one end is electrically connected to the ground substrate, and which has a plate shape being parallel to the ground substrate; and
a connecting portion which electrically connects another end of the first conductor device and another end of the second conductor device to each other, wherein
a width of the first conductor device is wider than a width of the second conductor device, and
lengths of the first conductor device and the second conductor device are ½ of a wavelength of a radio wave for operating the antenna apparatus, wherein
a grounded metal member is further provided at a distance of 1/50 or less of the wavelength of the radio wave for operating the antenna apparatus from at least one of the one end of the first conductor device and the connecting portion.
