摘要： An antenna includes: a radiating element that is formed of a conductor and radiates electromagnetic waves when supplied with electrical power; and a parasitic element that is (i) formed of a conductor, (ii) provided near the radiating element so as to be electromagnetically coupled with the radiating element, (iii) provided in a plane substantially perpendicular to a plane including the radiating element, and (iv) guides the electromagnetic waves without being supplied with electrical power.

摘要： 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.

摘要： 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.
