Abstract

Provided are a waveguide forming apparatus having an optimized circuit section and a high versatility, a dielectric line forming apparatus, a pin structure and a high frequency circuit. A waveguide is formed by operating first and second conductive layers (6, 7) together with a plurality of control pins (2). A variable high frequency circuit forming section is freely and simply changed by displacing each control pin (2) over a down-status shown by Z1 and an up-status shown by Z2.

Description

technical field [0001] The present invention relates to a waveguide forming device, a dielectric line forming device, a pin structure, and a high-frequency circuit, and relates to technologies suitable for application to high-frequency circuit devices such as antennas, filters, and coupling circuits. Background technique [0002] In recent years, research on software radio circuits has become popular (see Japanese Patent No. 3686736, Japanese Patent No. 3439973, Japanese Patent No. 3517097, Japanese Patent Laying-Open No. 11-284409, and Japanese Patent No. 3420474). For example, by replacing the existing software of the mobile terminal and changing the configuration, the mobile terminal can be changed into various modes such as a car navigation system, a ground wave TV receiving terminal, and the like. For the specific implementation of the software wireless technology, large-scale field programmable gate array (referred to as FPGA), high-speed digital signal processor (refe...
