Description

Technical Field

[0001] The present invention relates to the technical field of antenna products, in particular to a distributed antenna. Background Art

[0002] The frequency bands of the existing indoor ceiling antennas are 698MHz-960MHz&1710MHz

[0003] The antennas used for initial installation only cover frequencies from 698MHz to 960MHz and 1710MHz to 2700MHz. This means they cannot meet performance requirements for applications requiring more frequency bands. For example, performance in these bands, such as 410MHz, 433MHz, 450MHz, 1400MHz, 3400MHz-3800MHz, 4900MHz-5850MHz, and 5925MHz-7125MHz, is poor, or they only have one output port, making them incapable of supporting full-band and MIMO applications. The antennas used for initial installation only cover frequencies from 698MHz to 960MHz and 1710MHz to 2700MHz. Subsequent additions to new application bands require antenna replacement, increasing labor and costs. Currently, commercially available antennas generally offer a gain of 2-3dBi and an efficiency of around 60%. These antennas are complex and require numerous steps. Expanding the frequency bands also increases the height and width of the antennas, significantly impacting aesthetics and potentially discouraging users. Therefore, at this stage, it is necessary to develop an antenna that can meet the application scenarios from 400MHz to 7.2GHz, with high gain, high efficiency, low profile, simple structure, good consistency, beautiful appearance, and one antenna with two ports, simple and convenient construction, small space occupation, significantly reduced costs, and high acceptance among ordinary users.
