Embodiment Construction

[0022] like 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 serves as the ground of the antenna. 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] like 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...

Abstract

The optically controlled solid-state plasma reconfigurable antenna based on transparent media and conductive materials provided by the present invention is a new type of reconfigurable antenna that can realize frequency reconfigurability, pattern reconfigurability, and polarization reconfigurability. It includes a photosensitive material layer, a photosensitive material unit, an insulating isolation structure, a transparent medium layer, a transparent conductive material layer, and a laser. Wherein the photosensitive material layer includes a photosensitive material unit and an insulating isolation structure. The present invention uses a transparent medium and a transparent conductive material as the medium and ground of the antenna. And the laser is used to excite at the bottom, which realizes the photoelectric isolation well, and also solves the influence of the traditional reconfigurable antenna bias circuit on the antenna radiation.

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...
