Problems solved by technology

On the one hand, the combination principle of single-parameter reconstruction technology is easy to implement, but the dimensions that can be optimized for reconstruction are small and the reconfigurability is low
On the other hand, the reconfigurable aperture antenna has high reconfigurability. Although it meets the reconstruction requirements of different types of parameters, it also has the problem of strong coupling of parameter reconstruction, which limits the practical application of the antenna.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a parameter mixing reconfigurable antenna. Background technique [0002] The structure and working parameters of traditional antennas are fixed, and it is difficult to meet the requirements of modern smart radio equipment for adapting to complex environmental changes. In the actual application environment, the technical indicators of radio equipment will be significantly reduced. Reconfigurable antennas can use optical, electrical or mechanical means to change the distribution of antenna surface currents to achieve flexible adjustment of operating frequency, pattern and / or polarization parameters. Compared with the complex phased array antennas of expensive systems, the reconfigurable antennas based on radio frequency switches can provide a low-cost technical approach for the realization of smart antennas for radio equipment to adapt to complex environmental changes or human int...
