Abstract

The invention provides a mini enhanced dual-polarization omnidirectional ceiling antenna. The antenna comprises a single cone, a horizontal polarization unit and a step-shaped floor which are arranged in a vertically coaxial and centrally overlapped manner from top to bottom successively, the single cone comprises a first single cone radiator and a second single cone radiator which are arranged in a crossing manner, the bottom of the single cone is provided with a feed point, and a coaxial feed cable is connected to the feed point in the bottom of the single cone by penetrating the step-shaped floor and the horizontal polarization unit from bottom to top successively. Within the frequency range from 0.8GHz to 2.70GHz, the single-cone ceiling antenna realizes effective impedance match, an ideal omnidirectional radiation performance, a substantial edge coverage enhanced effect, a consistent in-band coverage range, higher efficiency, higher port isolation degree (better than -24dB), small size and low profile and is suitable for indoor coverage. The antenna is also characterized by being novel in ideas, clear in principles, universal in methods, easy to realize, low in cost and suitable for batch production, the antenna can be used to replace a routine dual-polarization omnidirectional ceiling antenna, and can be used for design and improvement of a vertical-polarization enhanced omnidirectional ceiling antenna and a planar Alford loop antenna.

Description

【Technical field】 [0001] The invention relates to an indoor distributed coverage antenna device and technology for cellular mobile communication, in particular to a miniaturized enhanced dual-polarized omnidirectional ceiling antenna and its technology. 【Background technique】 [0002] Indoor environments have become hotspots for traffic and data traffic. It is difficult for outdoor macro base stations to provide deep and accurate coverage inside buildings. Naturally, people miniaturized the outdoor base stations and deployed them in various places inside the building, forming an indoor distributed coverage system. Considering factors such as capacity, site selection, and cost, the indoor small base station must support multiple standards (GSM2G / CDMA-3G / LTE-4G), full frequency band (800-960MHz / 1710-2700MHz), and the horizontal plane needs to cover more large area. Restricted by the installation location, indoor antennas usually fall into two categories: directional wall mo...
