Abstract

The invention relates to an adjustable polarization converter and an electronic device. The adjustable polarization converter comprises a first substrate, a second substrate and a liquid crystal layerarranged between the first substrate and the second substrate. The first substrate comprises a first base substrate and a first electrode arranged on the first base substrate; and the second substrate comprises a second base substrate and a second electrode arranged on the second base substrate. The first electrode comprises a conductive border and two triangular conductive patches; the conductive border comprises two notches sequentially formed; and two triangular conductive patches are arranged in a region surrounded by the conductive border and are centrally symmetric. The adjustable polarization converter can implement polarization conversion on an incident electromagnetic wave under a relatively high frequency, and has the advantages of simple structure, high response speed, high working frequency, large working frequency range and the like.

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...
