Dual-polarization dielectric antenna and base station antenna array thereof

Abstract

The invention discloses a dual-polarization dielectric antenna and a base station antenna array thereof. The dual-polarization dielectric antenna is used for radiating electromagnetic waves to space and receiving the electromagnetic waves from the space, the antenna comprises a grounded base plate and a dielectric resonator arranged on the grounded base plate, and a crossed feed structure enveloped by the dielectric resonator, wherein the crossed feed structure performs feeding through a differential feed network, and the differential feed network is arranged on the back of the grounded base plate; when the dielectric resonator and the crossed feed structure are simulated through electric signals of the differential feed network, a combination of the dielectric resonator and the crossed feed structure is set to mainly radiate the electromagnetic signals related to the electric signals right above the grounded base plate in a unidirectional mode. The dual-polarization dielectric antennaprovided by the invention has high radiation front-to-rear ratio, is simple in structure, convenient to mount and very suitable for application of a large-scale antenna array, and has very high commercial application foreground.

Description

technical field [0001] The invention relates to the field of radio frequency communication, in particular to a dual-polarized dielectric antenna and a base station antenna array thereof. Background technique [0002] In the past ten years, the Internet of Things has gradually entered the lives of the public. As an emerging industry, the Internet of Things uses the Internet and traditional telecommunication networks to interconnect all ordinary objects that can perform independent functions to form a huge all-encompassing network. In this network, not only objects can communicate with each other and cooperate with each other, but also objects can form effective interactions with people and the surrounding environment. The implementation of the Internet of Things needs to assign a unique label to each object in the network. As an important part of the Internet of Things technology, radio frequency identification technology is very suitable for applications in certain scenari...

Problems solved by technology

However, compared with some circuit-printed antennas, the structure of the dielectric antenna is more complicated, and the cost of the antenna is also more expensive.

Another problem with dielectric antennas is that when the antenna height is low, the front and rear suppression of the antenna is relatively large; therefore, the communication quality of dielectric antennas applied to dual-polarized antennas is still not ideal. If this problem is not solved, it will not be possible Meet the higher standard communication quality requirements of future base station antennas
