Embodiment Construction

[0029] The space phase shifter for analog signal processing based on the metasurface proposed by the present invention is formed by periodically arranging a basic unit. Such as figure 1 (a) to figure 1 As shown in (b), the basic unit of this spatial phase shifter is composed of four layers of ring-shaped metal patch structures cascaded with four layers of dielectric substrates and the last layer of complete metal patches. By designing the size of the metal patch structure and The thickness of the dielectric substrate and the relative permittivity can obtain the required group delay response spatial phase shifter structure.

[0030] figure 1 (c) shows a schematic diagram of the ring-shaped metal patch structure in the present invention. The parameters that determine its size are: the length Px and width Py of the basic unit, the width w of the rectangular metal ring, and the length Lx and width Ly of the middle rectangular metal patch.

[0031] figure 1 (d) shows the side ...

Abstract

The invention discloses a basic unit and a spatial phase shifter for analog signal processing based on the basic unit, comprising: n*n basic units, n*n basic units are arranged periodically, each unit contains a five-layer metal structure and The four-layer dielectric structure, through the carefully designed structure, makes electromagnetic signals of different frequencies generate different group delays, thereby realizing analog signal processing. In the present invention, the space phase shifter with step-type group delay response has the function of pulse position modulation, and the space phase shifter with linear group delay response has the function of pulse stretching. The invention has simple principle, low manufacturing cost and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of analog signal processing and new artificial electromagnetic materials, in particular to a basic unit and a spatial phase shifter for analog signal processing built on the basis of the basic unit. Background technique [0002] Analog signal processing devices can directly process ultra-wideband signals in real time in a very high frequency band. In contrast, digital signal processing devices require an ultra-high sampling rate when processing broadband signals, which brings great hardware complexity and high cost. The core of an analog signal processing device is a dispersive delay structure or a phase shifter that can provide the required group delay response. At present, the algorithm for synthesizing the phase shifter with the required group delay response at the transmission line level is relatively mature, and can obtain phase shifters with different group delay responses such as ladder, linear and t...
