Abstract: Provided is an antenna device with a simple configuration and in which it is possible to control the directivity in various directions. An antenna device according to the present invention is provided with: an array antenna that includes at least one antenna element disposed on a first surface of a substrate and that forms beams in respective directions having a plurality of angles including a first angle relative to the first surface of the substrate; and a side wall that is provided on at least a partial periphery of the at least one antenna element and that refracts, in a direction along the substrate, a first beam in the direction having the first angle.

Abstract: Provided is an antenna device with a simple configuration, said antenna device supporting a plurality of frequency bands. An antenna device according to the present invention is provided with: at least one first radiation element that has a resonant frequency in a first frequency band; at least one second radiation element; and a connection line for connecting the first radiation element and the second radiation element. The line length formed of the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonant frequency in a second frequency band lower than the first frequency band.

Abstract: A wireless module includes a substrate, a ground pattern disposed on the substrate, a first antenna, a second antenna, and a base plate that is conductive. The first antenna is disposed between one end of the substrate and the ground pattern, and includes a grounding part and a first power feeding part, the grounding part is connected to the ground pattern, and the first power feeding part is fed with a first signal. The second antenna is disposed between the other end of the substrate and the ground pattern, and includes a second power feeding part fed with a second signal. The base plate includes a first opposed portion that faces the first antenna, a second opposed portion that faces the second antenna, and a third opposed portion that faces the ground pattern and is short-circuited to the ground pattern. The base plate also has, on the third opposed portion, a short-circuit point at which the base plate and the ground pattern are short-circuited to each other. The short-circuit point is disposed on the third opposed portion at a position nearer to the first opposed portion than to the second opposed portion.

Abstract: Provided is an antenna device with a simple configuration, said antenna device supporting a plurality of frequency bands. An antenna device according to the present invention is provided with: at least one first radiation element that is provided on one surface of a substrate and that has a resonant frequency in a first frequency band; at least one second radiation element provided on the one surface of the substrate; a connection line for connecting the first radiation element and the second radiation element on the one surface of the substrate; a conductor that is provided at a position facing the first radiation element in the interior of the substrate and that has a slot; and a power supply line for supplying power to the first radiation element via the slot. The connection line is connected to the center portion, of the first radiation element, in a direction along the direction of polarization of radio waves radiated due to resonance. The line length formed of the first radiation element, the connection line, and the second radiation element is set to a length so as to have a resonant frequency in a second frequency band lower than the first frequency band.
