Problems solved by technology
[0003]In the past beam control methods, the directional antenna is mainly equipped with a mechanical turntable or manual rotation to achieve the change of the antenna beam directivity, which is not efficient and accurate enough
There are also phased array antennas, which realize beam scanning and switching by changing the feeding phase of the radiating elements in the phased array antenna. However, the overall structure of the antenna is very complicated whether it is fed by transmission lines or space. Increases the possibility of potential problems, and the overall cost is very high

The invention provides a substrate integrated waveguide-based adjustable array antenna, and the antenna comprises an upper dielectric substrate and a lower dielectric substrate; the upper surface and the lower surface of the upper dielectric substrate are respectively covered with a first metal layer and a second metal layer; the upper dielectric substrate is provided with a first metalized through hole, and the first metalized through holes are distributed along the edge of the upper dielectric substrate to form a closed array frame; the first metalized through holes penetrate through the first metal layer, the upper dielectric substrate and the second metal layer to form a substrate integrated waveguide cavity, and the substrate integrated waveguide cavity comprises multiple columns of substrate integrated waveguides arranged in the cavity. The upper dielectric substrate is provided with multiple columns of slot units penetrating through the upper dielectric substrate, and the multiple columns of substrate waveguides radiate signals outwards through the slot units. By adopting the feed-in slot array, the freedom degree of beam control is higher, the overall size of the antenna is greatly reduced, the manufacturing cost of the beam-adjustable antenna is reduced, and the application possibility of the beam-adjustable antenna in more scenes is expanded.
Description
technical field [0001] The present application relates to the field of electromagnetic microwave technology, in particular to a controllable array antenna and a terminal based on a substrate integrated waveguide. Background technique [0002] In the field of electromagnetic waves, the antenna can be regarded as a transformer, which can convert the guided wave on the transmission line into an electromagnetic wave in free space, and similarly convert the electromagnetic wave into a guided wave. Therefore, in modern wireless communication systems, as long as the application of electromagnetic waves is involved, whether it is to use electromagnetic waves to transmit information or use electromagnetic waves to transmit energy, antennas, as a conversion medium, are always an indispensable part. Generally speaking, the antenna itself is reversible and follows the reciprocity theorem, that is, it can be used as both a transmitting antenna and a receiving antenna, and the performance...
