Abstract

The invention provides a capacitor structure, wherein a signal electric conduction polar plate and an extension grounding electric conduction polar plate are arranged on the same plane to form a co-plane capacitor. By utilizing physical property of slow wave, the capacitor structure can effectively improve resonance frequency of capacitor elements, and make the capacitor elements capable of being applied to higher frequency range.

Description

technical field [0001] The invention relates to a capacitor coplanar structure, which arranges the signal conductive electrode plate and the extended ground conductive electrode plate on a plane. Background technique [0002] With the advancement of electronic products, thin, light, compact and multi-functional products have become the mainstream trend in the market. Reducing the size and number of components has become the focus of product design. Embedded passive component technology can replace traditional stand-alone passive components, and use new polymer composite material technology to bury passive components in the inner layer of printed circuit boards by means of coating, screen printing, lamination, etching, etc. . [0003] In embedded passive component technology, capacitors have always been valued, controlling the size and price of system modules. However, the parasitic effect of this type of capacitor makes the capacitance value of the capacitor change non-lin...
