Problems solved by technology
[0003] In order not to use the beamforming feed network, some existing technologies can also achieve multi-beam coverage by exciting single-arm helical antennas or multi-arm helical antennas, but it is necessary to introduce diodes to control beam switching, which introduces more losses; in addition Some designs can also generate four beams pointing to four quadrants in the horizontal plane by exciting a square loop antenna or a square patch antenna, but the number of beams is small and the coverage is limited

Abstract
The invention discloses a multi-beam antenna without a feeding network and a manufacturing method thereof. The multi-beam antenna comprises a hexagonal first dielectric substrate and a second dielectric substrate, a surface wave guide, and a surface wave guide arranged on the upper surface of the second dielectric substrate. The patch array and the metal ground layer disposed on the lower surface of the second dielectric substrate, the shapes of the first dielectric substrate and the second dielectric substrate are both hexagonal, and the first dielectric substrate and the second dielectric substrate are all overlapped and superimposed on each other. Together, the lower surface of the first dielectric substrate is opposite the upper surface of the second dielectric substrate. The present invention has the advantages of beam inclination, wider bandwidth, low profile, high gain, multi-directional coverage, etc., can avoid the complexity and extra space brought by the beamforming network, and thus has a high degree of integration. The present invention is widely used in the technical field of wireless communication.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-beam antenna without a feeding network and a manufacturing method thereof. Background technique [0002] With the rapid development of wireless communication technology, it has become a necessary development trend to provide services for more users within limited spectrum resources. The multi-beam antenna can control the deflection direction of the beam to generate strong beams in the specified communication direction, and generate weak beams in other interference directions. Therefore, the strong beams generated by the multi-beam antenna in different directions can improve the utilization rate of the system and the data transmission rate, and increase the system capacity and spectrum utilization; at the same time, the weak beams generated by the multi-beam antenna in the interference direction can improve the multipath fading. and multipath interference p...
