Description

Technical Field

[0001] The utility model belongs to the technical field of communication antennas, and in particular relates to a communication antenna suitable for use along a subway line. Background Art

[0002] With the construction and use of more and more subways and light rails, people are enjoying the convenience and speed brought to their lives by the rapidly developing urban rail transit. At the same time, in order to achieve large-scale coverage of wireless networks, antennas need to be installed in multiple locations. The antenna is a component exposed outside the system, so the impact of the environment on the performance of the antenna is of great significance. In all stages of antenna design, testing and use, full attention must be paid to the impact of environmental conditions.

[0003] The communication direction along the subway line is mainly radiated along the direction of the subway track, but the radiation communication direction of the existing communication antenna is radiated in all directions, which has a poor radiation effect in the communication direction of the subway track, thereby resulting in poor communication effect of the communication antenna, affecting the communication effect of the subway. For this reason, we propose a communication antenna suitable for the subway line. Utility Model Content
