Abstract

The invention provides a power supply EBG structure based on open-loop resonators and an X-shaped bridge. The power supply EBG structure comprises two metal layers and one dielectric layer, wherein the dielectric layer is arranged between the two metal layers; the upper metal layer is a power supply layer; the lower metal layer is a ground layer; the upper metal layer, namely the power supply layer, utilizes etching open-loop resonators as periodical units of an EBG structure; the open-loop resonators are connected through an X-shaped bridge; the lower metal layer utilizes a complete metal plane; and the open-loop resonators are adjusted by means of adjusting of the size of the open-loop resonators. For the power supply EBG structure based on open-loop resonators and an X-shaped bridge, two metal layers are utilized to design the EBG structure and the periodical units of the structure utilize complementary open-loop resonators and uses the X-shaped bridge to connect the periodical units so as to increase the bandwidth of a stop band and restrain the depth, so that effective suppression of electromagnetic noise can be realized in a broadband range.

Description

technical field

[0001] The invention is a novel ultra-broadband power supply EBG structure, which belongs to the field of electronic information technology. It is mainly used for the power supply plane of high-speed / microwave printed circuit, suppresses the electromagnetic interference noise between the power supply / ground plane, and realizes good power supply integrity . Background technique

[0002] Modern circuit systems integrate digital circuits, radio frequency circuits, analog circuits, etc. The integration density is getting higher and higher, and the operating frequency is getting higher and higher. The electromagnetic interference of the power supply and ground network is also becoming more and more obvious, which has a bad impact on the performance of the system. , must be suppressed. In the power ground network, a plane pair structure is formed between the power plane and the ground, and various resonances are generated within a certain frequency range. In addi...
