Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a hybrid orthogonal source array antenna. Background Art

[0002] With the development of wireless communication technology, the requirements for antennas are getting higher and higher, especially in the application of satellite navigation systems (such as GPS, GLONASS, Galileo, Beidou, etc.), which require antennas to have good reception performance, wide bandwidth and miniaturization. At present, the anti-interference array antennas in the industry all use regular microstrip patch antennas. When the array spacing is less than half a wavelength, a certain structural isolator will be adopted to reduce the coupling between the same-frequency array elements. Because the setting of the isolator follows the frequency variation law, the size of the isolator cannot be infinitely small, and there are certain requirements for the size of the array antenna. Therefore, it is particularly important to develop a hybrid orthogonal source array antenna that can solve the problem of array element isolation under a smaller size and has high directivity and gain. Summary of the invention

[0022] As an example, to solve the problem of poor isolation under the miniaturization of anti-interference antennas, this embodiment starts from the design of the antenna radiation source and adopts an array form mainly based on different radiation current sources: the vertical radiation source 2 includes two elements arranged in a straight line, the horizontal radiation source 3 includes two elements arranged in a straight line, each element is respectively connected to the RF cable at its rear end, and finally connected to the signal processing module; by orthogonally arranging the vertical radiation source 2 and the horizontal radiation source 3 on the bottom plate 1, using the orthogonal arrangement of different polarization radiation sources, the coupling problem between co-frequency elements can be effectively reduced, further meeting the requirements of miniaturized array layout, effectively solving the element isolation problem under more miniaturized conditions, and thus ensuring key indicators such as the gain and axial ratio of the antenna.
