摘要： A wireless communication device includes a reflecting plate having a reflecting surface that reflects electromagnetic wave, a radome covering the reflecting plate so as to form an airflow path between the radome and the reflecting surface, and including an air inlet and an air outlet communicating with the airflow path, an array antenna provided on the reflecting surface and inside the airflow path, and including a plurality of antenna elements aligned on the reflecting surface with an interval from each other, and a communication circuit that transmits and receives a wireless signal by exciting the array antenna. The plurality of antenna elements each include an antenna pattern formed on a plate-shaped dielectric substrate extending from the reflecting surface in a direction orthogonal thereto. Dissipation effect of heat from the communication circuit can be improved, by causing air convection in the airflow path in the radome.

摘要： Provided are an antenna, an antenna array, and a wireless communication device with which it is possible to achieve size reduction while suppressing degradation in radiation efficiency. This antenna comprises two antenna elements and a conductor reflection plate. The antenna element includes: a C-shaped conductor which is a substantially C-shaped conductor in which a split part is formed such that a portion of an annular conductor is made discontinuous; and a conductor power feed line that is electrically connected to one of the two parts of the C-shaped conductor that oppose one another across the split part, the conductor power feed line constituting an electric circuit for feeding power to the C-shaped conductor. The two antenna elements are arranged substantially orthogonal to one another such that, when the elements are projected onto the conductor reflection plate, one antenna element and a portion of the other antenna element overlap one another.

A different end of the first branch part (5a) and a different end of the second branch part (5b) face each other and form a capacitor part. The capacitor part is positioned outside the area surrounded by the connection element (7), the first radiant element (3), and the second radiant element (4). Part of the first radiant element (3), part of the second radiant element (4), the first branch part (5a), the second branch part (5b), and the capacitor part form a split ring resonator (8).
