Description

Technical Field

[0001] The utility model belongs to the technical field of antennas, and in particular relates to a single-medium coupled integrated ultra-wideband combined antenna. Background Art

[0002] With the development of global satellite navigation and satellite communication systems, there are more and more systems, and each system uses more and more frequency bands, and each system requires independent frequencies to realize its respective functions.

[0003] Traditional stacked antenna technology requires one layer to be superimposed at one frequency, which makes the antenna larger and larger, the number of stacked layers increases, the thickness increases, and the cost increases. The previous single-medium wideband antenna can handle two frequency bands with relatively close frequencies. Because the frequencies of the two frequency bands are close, mutual coupling will be formed, which will greatly reduce the quality of the antenna signal. Or when the system requires multiple frequency bands to be used, it is necessary to continue to superimpose stacked or single-medium antennas of other frequencies on the antenna. However, due to their own structural reasons, traditional products are difficult to make room for the superimposed antennas. In addition, traditional stacked or early single-medium antennas either have a large number of feeds due to independent output of high and low frequencies, or can only use four-feed output due to poor axial ratio and insufficient bandwidth when using dual feed points. The back-end PCB space is relatively limited, and it is difficult to make room for multiple feeds. The more output feeds, the more difficult it is to make room. The more feeds, the more combiners or bridges are used, the higher the cost, and the more combiners or bridges have accumulated insertion losses, which reduces performance.

[0004] Therefore, a combination antenna with low axial ratio, less feed, and wide bandwidth is needed to replace the existing antenna, so that the combination antenna uses fewer feeds, fewer combiners or bridges, and achieves a larger bandwidth output with lower cumulative insertion loss and lower cost, and has fewer restrictions on usage scenarios.
