Abstract
An antenna device is provided with a first connecting electrode, a first tunnel diode, a first antenna member and a fixed electrode. The first connecting electrode is configured to be connected to a fixed potential via a load. The first tunnel diode has a pair of electrodes. One of the electrodes of the first tunnel diode is connected to the first connecting electrode, and the other electrode of the first tunnel diode is connected to the first antenna member. The first antenna member has a conductive property and includes a first portion and a second portion. The first portion of the first antenna member is connected to the other electrode of the first tunnel diode. The fixed electrode is connected to the second portion of the first antenna member. The fixed electrode is configured to be connected to the fixed potential.
