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.

Abstract: A ceiling-mount omni-directional antenna for indoor distribution system of mobile communication network and a method for manufacturing the same are provided. The antenna includes: a monopole consisting of a cone part and a columnar part, and a reflecting plate consisting of a cone part and a platform part, and a feed connector. The monopole and the reflecting plate are arranged in such that the tips of cone parts are opposite to each other. The signal is fed into the antenna through the feed connector and radiated outward by the monopole and the reflecting plate. In high frequency band, the maximal gain appears at about 70°, so that the signal power focuses at radiating angles of 60°-85°. The gain of the antenna increases 4.22 dB at a radiating angle of 85° and decreases IOdB at a radiating angle of 30°.

The signal is fed into the antenna through the feed connector and radiated outward by the monopole and the reflecting plate. In high frequency band, the maximal gain appears at about 70°, so that the signal power focuses at radiating angles of 60°˜85°. Comparing to the existing antenna, the gain of the antenna increases 4.22 dB at a radiating angle of 85° and decreases 10 dB at a radiating angle of 30°.
