Abstract

An omni directional antenna is provided in the embodiments of the present invention. The antenna includes: at least two metal plates, at least one metal reflecting plate, a feed circuit, and plural first enclosure devices; the at least one metal reflecting plate is located inside the enclosed or half-enclosed cavity formed by the at least metal plates and is parallel with each metal plate; and the metal plates and the metal reflecting plates, which are parallel with each other, are enclosed at the edges by the first enclosure devices alone the width direction, so that the metal plates and the metal reflecting plates, which are parallel with each other, are electrically connected; the feed circuit is located among the metal plates and the metal reflecting plates, which are parallel with each other; and among the metal plates and the metal reflecting plates, which are parallel with each other, the electromagnetic wave generated by the feed circuit is reflected to the metal plate by the metal reflecting plate, and the electromagnetic wave radiated to the metal plate from the feed circuit and the electromagnetic wave reflected to the metal plate by the metal reflecting plate are radiated outward by slots in the metal plate. The embodiments of the present invention have improved the out-of-roundness index of the antenna, and thus improved the radiation performance of the antenna.
