Abstract:
The present disclosure relates to radio engineering, and more specifically to high-frequency (HF) signal transmission/reception devices based on photoconductive switching elements. An HF signal transmission/reception device comprises a signal electrode with matching elements disposed along an edge thereof; a ground electrode, a dielectric layer between the signal electrode and the ground electrode, photoconductive elements (PE) each electrically connected to the signal electrode and the ground electrode and arranged in a grid, an excitation signal feed point, and load elements electrically connected to the matching elements. The photoconductive elements each have a switched-off state in the absence of a control light flux and a switched-on state in the presence of a control light flux, The switched-on photoconductive elements form a reflection profile of the signal supplied from the excitation signal feed point. The distance between adjacent photoconductive elements is less than half the wavelength of the excitation signal.

Claim (Index 12):
A high-frequency signal transmission/reception device, comprising:\n a signal electrode that includes a form of a flat conductive plate; a ground electrode that includes a form of a flat conductive plate and is disposed parallel to the signal electrode; a dielectric layer that is disposed between the signal electrode and the ground electrode and includes a thickness of not less than a quarter wavelength of a signal to be transmitted/received; a plurality of photoconductive elements that are arranged in holes in the dielectric layer and are arranged in a grid; a plurality of optical waveguide portions, each of which is in contact with a respective photoconductive element across a thickness of the dielectric layer and provides a control light flux thereto; and an excitation signal feed point, wherein: the photoconductive elements are each electrically connected to the signal electrode and the ground electrode, includes a thickness equal to the thickness of the dielectric layer, are included at least in two states, the at least two states including a dielectric state with a low intrinsic electrical conductivity (switched-off state) in absence of a control light flux, and a conductor state with a relatively high electrical conductivity (switched-on state) in presence of a control light flux, the photoconductive elements in the grid are arranged such that the photoconductive elements, to which a control light flux is applied at a given instant, form a curve close to a desired reflection profile of an excitation signal supplied from the excitation signal feed point, a distance between adjacent photoconductive elements is less than a half of a wavelength of the excitation signal, and at least one of the signal or ground electrodes includes holes to supply optical waveguides to the photoconductive elements.
