摘要： An antenna device includes a ground electrode, a feed element, and a parasitic element. The ground electrode has a substantially non-square rectangular plane shape that includes a first side extending in a first direction and a second side extending in a second direction orthogonal to the first direction. The feed element has a substantially rectangular plane shape and is formed in such a way that each side of the feed element becomes parallel to the first direction or the second direction. The parasitic element is formed in such a manner as to face a side of the feed element parallel to the first side. The feed element is configured to radiate a first polarized wave that excites in the first direction and a second polarized wave that excites in the second direction. The length of the first side is longer than the length of the second side.

摘要： A two-port antenna system is proposed that uses a polarization-independent spatial power divider to align the beams from two orthogonally oriented dual-polarized feeds. This antenna system is compatible with fully polarimetric radar and provides high port isolation. It simultaneously provides a common aperture for transmit and receive to minimize radar parallax. The spatial power divider is designed using a combination of all-dielectric metamaterial techniques and the concept of miniaturized-element frequency selective surfaces, and is fabricated on a silicon wafer using standard microfabrication technology.

摘要： The present invent discloses an electrically-controlled switching multi-polarization horn antenna, which relates to the technical field of communication antennas. The horn antenna includes a horn antenna body, a polarization controller and a polarization switching apparatus. The horn antenna's control module controls a linear polarization control generation module, a circular polarization control generation module and a polarization selection module to cause the horn antenna to operate in a horizontal polarization mode, a vertical polarization mode, a left-hand circular polarization mode or a right-hand circular polarization mode. The antenna can realize a quick switch between different polarization modes, and the switch is electrically controlled rather than performed by manually replacing the antenna. Using the antenna of the present invent can effectively shorten test time, reduce the number of times replacing antennas by a tester, and more accurately measure characteristics of a device under test in various polarization modes.
