A printed circuit board-integrated antenna for transmitting/receiving data, the antenna comprises an intermediate section comprising patch elements interconnected by at least one via, wherein a first patch element is disposed in a lower middle layer and is separated by a gap from a conductive solid area, a second patch element is disposed in an upper middle layer and is separated by a gap from the conductive solid area; a parasitic patch element disposed in an upper layer and separated by a gap from the conductive solid area; and a strip line connected directly to an edge of the first patch element, the strip line being disposed in the lower middle layer and configured for communicating a data signal to or from the intermediate section when transmitting/receiving data. The disclosure provides a simplified antenna configuration, for the implementation of which the minimum number of layers is used in the printed circuit board.

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.
