Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a dual-polarization downlight type antenna. Background Art

[0002] In some specific areas, especially inside buildings, traditional ceiling antennas may cause objection from owners and residents. Beautifying antennas can better blend into these environments and reduce disputes.

[0003] On the other hand, the antenna vibrator is a conductor installed on the communication antenna module, and the antenna vibrator is responsible for converting high-frequency current into electromagnetic waves. In wireless communications, antenna vibrators are usually made of copper or aluminum, and the shape and size of the antenna vibrator depend on the required operating frequency and the type of antenna. Traditional indoor antenna vibrators are mostly conical. If an indoor antenna frequency band covers a range of 800-2700MHz, then it is mainly suitable for 4G networks and communications in lower frequency bands. To support 5G networks, higher frequency band antennas are required. The mainstream frequency band range of 5G is 2600MHz-3700MHz.

Downlight antennas are a type of beautification antenna, mainly installed inside buildings. They can not only provide lighting, but also achieve signal coverage, cleverly combining antennas and downlights. Utility Model Content
