Abstract

An adjustable polarization converter and electronic device. The adjustable polarization converter includes a first substrate, a second substrate and a liquid crystal layer arranged between the first substrate and the second substrate. The first substrate includes a first base substrate and a first electrode disposed on the first base substrate; the second substrate includes a second base substrate and a second electrode disposed on the second base substrate. The first electrode includes a conductive frame and two triangular conductive patches, the conductive frame includes two gaps arranged in sequence, and the two triangular conductive patches are arranged in the area surrounded by the conductive frame and are center-symmetrical. The adjustable polarization converter can realize the polarization conversion of incident electromagnetic waves at a higher frequency, and has the advantages of simple structure, fast response speed, high operating frequency, and large operating frequency range.

Description

technical field [0001] Embodiments of the present disclosure relate to a tunable polarization converter and an electronic device. Background technique [0002] The electromagnetic wave polarization converter is an important component in the antenna feeder system, which is of great significance for improving the channel capacity and signal-to-noise ratio of the wireless communication system. The function of the polarization converter is to change the polarization state of the incident electromagnetic wave into another polarization state, such as converting a linearly polarized electromagnetic wave into a circularly polarized electromagnetic wave, or converting a circularly polarized electromagnetic wave into a linearly polarized one. electromagnetic waves. [0003] Currently, according to the different input and output methods of electromagnetic signals, polarization converters can be divided into two types: space-fed polarization converters and forced-feed polarization conv...
