Abstract
An antenna device includes: a first antenna having a directional gain at a low elevation angle higher than the directional gain at a high elevation angle; a second antenna having the directional gain at the high elevation angle higher than the first antenna, transmitting and receiving a radio wave having a vibration direction of an electric field intersecting with a radio wave transmitted and received by the first antenna; and a third antenna having the directional gain at the high elevation angle higher than the first antenna, and transmitting and receiving a radio wave having a vibration direction of an electric field intersecting with the radio wave transmitted and received by the second antenna.
