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.

Abstract: By a wireless communication control device, a wireless communication device, a wireless communication control method, a predicted travel route of a vehicle is identified, access point information for identifying a position of an access point and a communication range is acquired. estimation information for estimating a transit time in a section on the identified travel route is acquired, a transit time required for the vehicle to pass through a communication range of the access point connectable to the wireless communication device on the identified travel route is estimated, and the access point causing the estimated transit time to be equal to or higher than a threshold is determined.
