Problems solved by technology
However, this method requires an additional complex feed network to feed the antenna array. On the one hand, the cost is high and the design difficulty of the antenna is greatly increased; on the other hand, the overall size of the antenna is too large to meet the miniaturization requirements of modern wireless communication systems. development trend

Abstract
The invention discloses a single-unit beam-forming dielectric resonant antenna, comprising: a first dielectric resonator; a second dielectric resonator arranged below the first dielectric resonator; a metal formation arranged on the second dielectric The resonator is below and has a feeding slot; the substrate is arranged under the metal formation; the feeding structure is arranged under the substrate and has a microstrip line, at least a part of the microstrip line is located in the feeding slot Directly below. In the present invention, by setting the first dielectric resonator and the second dielectric resonator as the radiation unit of the antenna, the feeding gap is set for the metal formation, and the radiation unit of the antenna is coupled and fed, avoiding the use of a complex feeding network, and in the feeding structure The microstrip line is arranged and at least a part of the microstrip line is located directly below the feeding slot, the feeding position and the excitation current distribution are provided, and beam forming is realized, the structure is simple and the size of the antenna is reduced, and it can be widely used in antenna technology field.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a single unit beam-forming dielectric resonant antenna. Background technique [0002] With the rapid development of wireless communication technology, the antenna as its core component has also been developed rapidly. At present, antennas have been widely used in various wireless communication devices, and play an important role in radar, personal communication, navigation, satellite communication and other systems. [0003] At present, the most common method of implementing beamforming antenna is to combine array antenna and beamforming feed network, and use the characteristics of phased array antenna to produce beams with different directions as the signal phase difference between the input ports changes. The beamforming network provides the appropriate input signal to the phased array antenna. When different ports of the beamforming feed network are excited, the phase diffe...
