Abstract
An antenna device includes an antenna array in which a plurality of antennas each including a negative differential resistance element and a resonance circuit are arranged, a voltage bias circuit which applies a voltage to the antenna array, a first shunt element which is connected between the antenna array and the voltage bias circuit in parallel relation to each of the negative differential resistance element and the voltage bias circuit, and in which a first resistor and a first capacitor of the first shunt element are connected in series, and a second shunt element which is connected between the first shunt element and the voltage bias circuit in parallel relation to each of the negative differential resistance element and the voltage bias circuit, and in which a second resistor and a second capacitor of the second shunt element are connected in series.
