Claim 0:
1. An antenna apparatus comprising:
a plurality of radiators arranged on a circumference of a first circle having a first radius;
a plurality of reflectors arranged on a circumference of a second circle which is concentric with the first circle, the second circle having a second radius larger than the first circle; and
a plurality of parabolic reflectors, wherein
the plurality of radiators are each configured to output a radio signal toward each of the plurality of reflectors along a radial direction of the second circle,
the plurality of reflectors each have a reflection surface inclined at a predetermined angle with respect to a circular plane and are each configured to reflect the radio signal output from a respective radiator toward an opposite antenna apparatus, and
the plurality of parabolic reflectors are each configured to reflect the radio signal output from a respective radiator such that the reflected radio signal is incident on a respective reflector.
