Embodiment Construction

[0022] Such as figure 1 , 2 As shown, the present invention is achieved through the following technical solutions. The present invention mainly includes a photosensitive material layer 1 , a transparent medium layer 4 , a transparent conductive material layer 5 and a laser 6 sequentially arranged from top to bottom; the transparent conductive material layer 5 acts as an antenna ground. The photosensitive material layer 1 is composed of insulating isolation structures 3 arranged in a mesh shape and photosensitive material units 2 individually arranged in each mesh hole.

[0023] Such as image 3 , 4 As shown, the photosensitive material unit 2 is excited by the laser 6, that is, the laser light emitted by the laser 6 passes through the transparent conductive material layer 5 and the transparent medium layer 4, and excites the photosensitive material unit 2 in the photosensitive material layer 1 to generate high-concentration carriers. Thus, photosensitive material units 2 w...

Abstract

The invention provides an optically controlled solid-state plasma reconfigurable antenna based on transparent medium and electrically conductive materials. Based on the technical scheme of the novel reconfigurable antenna provided in the invention, the frequency, the directional diagram and the polarization of the antenna are reconfigurable. The reconfigurable antenna comprises a photosensitive material layer, a photosensitive material unit, an insulated isolation structure, a transparent dielectric layer, a transparent electrically-conductive material layer and a laser. The photosensitive material layer comprises the photosensitive material unit and the insulated isolation structure. According to the technical scheme of the invention, the transparent medium and the electrically conductive materials are adopted as the medium and the materials of the antenna. Meanwhile, the laser is arranged at the bottom for excitation purpose, so that the photoelectric isolation effect can be well realized. The influence problem of the bias circuit of a traditional reconfigurable antenna on the antenna radiation can also be solved.

Description

technical field [0001] The invention relates to the field of reconfigurable antennas, in particular to an optically controlled solid-state plasma reconfigurable antenna based on transparent media and conductive materials. Background technique [0002] With the gradual improvement of the level of global informatization, the development of modern communication systems has entered a new era. The requirements for the antenna are also getting higher and higher, not only requiring the antenna to be small in size and low in energy consumption, but also requiring the antenna to have characteristics such as high gain, ultra-wideband, and multi-band. Traditional antennas have been difficult to meet the requirements of current communication systems, and reconfigurable antennas have emerged as the times require. The antenna frequency, pattern and polarization can be reconfigured by reconfiguring the antenna feeding structure and radiator. Contents of the invention [0003] The techn...
