Antenna device for communication base stations along high-speed railway

Abstract

An antenna device for communication base stations along a high-speed railway comprises a plurality of antennae, wherein the antennae are arrayed at the intervals in an extension direction of the high-speed railway and comprise 32-DEG narrow beam antennae, 65-DEG beam antennae, antenna feeder distribution systems and leaky cables; any 32-DEG narrow beam antenna, any 65-DEG beam antenna, any antenna feeder system or any leaky cable is connected with the communication base stations; and the communication base stations are connected in a mobile communication network. A planar antenna is arranged at an entrance of a tunnel where the high-speed railway passes, a macro base station is arranged outside the tunnel, and signals of the macro base station cover the tunnel through the planar antenna. According to the antenna device, the 32-DEG narrow beam antennae, the 65-DEG beam antennae, the antenna feeder distribution systems and the leaky cables are adopted according to topographies through which the high-speed railway extends, the area along the high-speed railway can be covered completely, communication dead zones are eliminated, and interrupted communication is avoided.

Description

Technical field: [0001] The present invention relates to the field of electricity, in particular to communication technology, in particular to an antenna for a communication base station along a high-speed railway, in particular to an antenna device for a communication base station along a high-speed railway. Background technique: [0002] The high-speed railway extends to form a narrow and long terrain scene, and the terrain it passes is complex. The wireless base stations are set in a chain structure, and the coverage area is linearly distributed. The train frequently crosses the residential area during high-speed driving, and the switching times are many. The speed of the high-speed railway is 200 to 250 kilometers per hour, which can be increased to 350 to 400 kilometers per hour. The high-speed movement of the user will bring obvious Doppler effect, frequent switching, weakened Rake receiver receiving ability and weakened channel equalization ability. High-speed railw...
