AI Technical Summary

Technical Problem

Conventional radio frequency filters face challenges in reducing thickness and weight due to the use of bonding processes and additional conductive structures, limiting their application in slim antenna devices and increasing insertion loss.

Method used

A filter for communication devices is designed with a foldable conductive base plate that forms a cavity and includes resonators, eliminating the need for bonding and additional structures, and is manufactured through a folding process to reduce thickness and insertion loss.

Benefits of technology

The filter achieves a slim and lightweight design by constructing a cavity through folding, reducing insertion loss and improving communication reliability without the need for conventional joining methods.

Abstract

The advantages of this type of connector include ease of slim manufacturing, reduced insertion loss, and improved resonance characteristics. The filter for a communication device includes a base plate made of a conductive material that is manufactured in an unfolded state and that is foldable to form a cavity therein when folded, and to position a plurality of resonators protruding a predetermined length in the thickness direction or width direction within the cavity. The plurality of resonators include a resonating characteristic end whose tip is bent perpendicular to the longitudinal direction of the remaining portion and has a wider width.
