Description

Omnidirectional microwave array antenna

This creation is about a omnidirectional microwave array antenna, especially for a microwave array antenna that can receive microwave signals in all directions.

Most of the traditional tracking antennas can only receive signals of a certain angle range, and it is necessary to rotate the tracking antenna to achieve 360-degree detection. If the detected object appears behind the tracking antenna at the first time, the traditional tracking antenna must be rotated to the direction of the object, and the tracking antenna can detect the exact position of the object. In addition, because the traditional tracking antenna can only detect objects within 360 degrees of the plane, it is usually used with the Global Positioning System (GPS). When the tracking antenna receives valid GPS data, the system will Automatically switch to tracking mode and start tracking the target.

Therefore, in summary, there is a tracking antenna that can replace the traditional tracking antenna and can receive the omnidirectional signal of 360 degrees and 120 degrees above without the assistance of the GPS positioning system and the special remote signal transmitting device.

The main purpose of this creation is to provide a reliable and low-cost omnidirectional microwave array antenna that can replace the traditional antenna tracking system.
