Problems solved by technology
Especially when the signal contains a DC component, there is a problem that the influence becomes larger
Also, when an electrical component using the liquid crystal dielectric layer 7 is used in a place where there is physical vibration, the dielectric constant of the liquid crystal dielectric layer 7 has a characteristic of changing with time. because sometimes there is a problem
Furthermore, in the conventional dielectric antenna disclosed in Patent Document 1, there is also a problem that it is difficult to stably control the dielectric constant.

Description
[0001] technology area [0002] The present invention relates to a liquid crystal component module that controls the dielectric constant of a liquid crystal dielectric layer formed of a dielectric material, and a method for controlling the dielectric constant of the liquid crystal component module. [0003] This application claims the priority of Japanese Patent Application No. 2004-367929 for which it applied on December 20, 2004, and uses the content here. Background technique [0004] Electronic components using dielectrics are often used in electronic devices using high frequencies (for example, microwave frequency bands), such as portable communication terminals in mobile communication systems. [0005] For example, in transmission circuits, resonant circuits, filter circuits, etc., using such as Figure 13 The microstrip line shown. This microstrip line is composed of a ground plane (ground line) 4, a conductor layer 1 (circuit pattern), and a dielectric layer 2 interpo...
