Problems solved by technology

[0003] Traditional optimization methods cannot break through the mutual constraints of physical size, bandwidth, and gain. Therefore, since the production of metamaterials in 2001, the use of metamaterials to improve the performance of antennas has attracted extensive attention and has been deeply studied.
However, there are limited methods for using metamaterials to improve antenna performance, and how to use the same unit structure to combine different methods to achieve a significant improvement in antenna performance is still a problem to be explored and solved.

Description

technical field [0001] The invention relates to the field of radio frequency microwave technology, in particular to a metamaterial unit and a double-layer radiation antenna device based on the metamaterial. Background technique [0002] The antenna is the entrance and exit of wireless communication and affects the performance of the wireless communication system. There are more and more types of antennas in the prior art. Microstrip antennas, as a typical representative of microwave frequency band antennas, have been widely used in various fields due to their small size and easy integration. However, the narrow bandwidth, low directivity and high loss of the microstrip antenna also restrict its use. With the continuous improvement of antenna performance requirements for various devices, designing high-gain and high-directivity microstrip antennas has become the focus of research. [0003] Traditional optimization methods cannot break through the mutual constraints of physi...
