Description

Single medium coupling integrated ultra-wideband combined antenna TECHNICAL FIELD

[0001] The present application belongs to the technical field of antennas, and particularly relates to a single medium coupling integrated ultra-wideband combined antenna. BACKGROUND

[0002] With the development of global satellite navigation and satellite communication systems, more and more systems are used, and each system uses more and more frequency bands, which all need independent frequencies to realize their respective functions.

[0003] Traditional laminated antenna technology needs to stack one layer for each frequency, so that the antenna size is getting larger and larger, the number of layers is getting more and more, the thickness is getting larger and larger, and the cost is getting higher and higher. The previous single medium wideband antenna can deal with two frequency bands close to each other, but the antenna signal quality will be greatly reduced due to the mutual coupling of the two frequency bands close to each other. Or when multiple frequency bands are required by the system, other frequency layers or single medium antennas need to be stacked on the antenna. However, due to the structure of the traditional product, it is difficult to avoid space for the stacked antenna. In addition, the traditional laminated or early single medium antenna either has a large number of feeders due to independent output of high and low frequencies, or can only use four feeders due to poor axial ratio and insufficient bandwidth caused by the use of double feed points. The rear-end PCB space is limited, and it is difficult to give space to multiple feeders. The more output feeders, the more difficult it is to avoid space, and the more feeders are used, the more combiners or bridges are used, the higher the cost, and the more cumulative insertion loss of the combiners or bridges, the lower the performance.

[0004] Therefore, a combined antenna with low axial ratio, few feeders and wide frequency band is needed to replace the existing antenna, so that the combined antenna uses fewer feeders, uses fewer combiners or bridges, realizes a larger bandwidth output with lower cumulative insertion loss and lower cost, and has fewer usage scene restrictions.
