Abstract
The present invention provides an omni-directional ceiling antenna, including: a cone cylinder-shaped radiation oscillator, a cone cylinder-shaped reflector, a disc cylinder-shaped base plate, and a dielectric ring; where the reflector includes a first hollow cone and a first cylindrical ring, a flared end of the first hollow cone is connected to the first cylindrical ring, and an outer diameter of the first cylindrical ring is smaller than that of the flared end of the first hollow cone; a second cylindrical ring is provided on the base plate, and the second cylindrical ring sockets to the first cylindrical ring to form a spatially separated coupling structure; the dielectric ring is provided between the second cylindrical ring and the first cylindrical ring so as to realize separation and fixed support between the reflector and the base plate.
