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 beamforming dielectric resonant antenna. The antenna comprises a first dielectric resonator, a second dielectric resonator which is arranged below the first dielectric resonator, a metal ground layer which is arranged below the second dielectric resonator and is provided with a feed slot, a substrate which is arranged below the metal ground layer, and a feedstructure which is arranged below the substrate and is provided with a microstrip line, and at least one part of the microstrip line is located right below a feed gap. According to the invention, thefirst dielectric resonator and the second dielectric resonator are arranged as radiation units of the antenna; the feed gap is formed for the metal ground layer; coupled feeding is carried out on a radiation units of the antenna; a complex feed network is prevented from being used; the microstrip line is arranged in the feed structure, and at least one part of the microstrip line is located underthe feed gap; a feed position and excitation current distribution are provided; beam forming is achieved; the structure is simple, and the antenna size is reduced and the antenna can be widely applied to the technical field of antennas.

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...
