Abstract
An antenna apparatus comprises, on a semiconductor substrate, a first active antenna including a first antenna configured to transmit or receive a first electromagnetic wave of a first frequency, and a first negative-resistance element; an oscillation unit including a resonance unit and a second negative-resistance element configured to generate a second electromagnetic wave by oscillating at a second frequency; a coupling wire configured to electrically connect the first active antenna and the oscillation unit; a first wiring electrically connected to the first negative-resistance element and configured to receive a first bias signal to be supplied to the first negative-resistance element; and a second wiring electrically connected to the second negative-resistance element and configured to receive a second bias signal to be supplied to the second negative-resistance element.
