An antenna apparatus is provided which has a centroid close to a vibration isolation structure and which is hard to vibrate like a pendulum motion when vibration is applied. The antenna apparatus includes a first base plate (5), an antenna unit (6) disposed at a side of the first base plate (5) and supported by the first base plate (5), and a counterweight unit (7) disposed at another side of the first base plate (5) opposite to the antenna unit (6) and supported by the first base plate (5). The antenna apparatus further includes a vibration isolation structure (8) having one end fixed to the first base plate (5) to suppress a vibration of the first base plate (5), and a second base plate (9) to which other end of the vibration isolation structure (8) is fixed and which is fixed to a moving object or a structural object. |
