Benefits of technology

The technical effect that this patented technology helps reduce sizeing on electronics components by making them smaller without compromising their performance or functionality.

Problems solved by technology

In this patented technical solution describes how to improve the performance (capacity) of high frequency electrical equipment such as radio communication systems due to their ability to efficiently transmit signals wirelessly across space while maintaining stable impedances against external interference caused by factors like vibrations. However, there can also happen where some parts of these components get too close together causing a small amount of air gaps within them. To solve this issue, the inventor proposes creating specific shapes called spirals around the entire structure instead of just one single spiraling type looped coils. These structures help reduce any changes made along its length compared to traditional designs but still allow enough room inside the device's volume to accommodate more wires.

Abstract

An electronic component includes a multilayer body including insulating layers stacked in a stacking direction, first and second linear conductors having different line widths and provided on a respective one of the insulating layers, and third and fourth linear conductors having different line widths and provided on a respective one of the insulating layers. The insulating layer(s) supporting the third and fourth linear conductors is/are at one side in the stacking direction of the insulating layer(s) supporting the first and the second linear conductors. In a planar view from the stacking direction, the first and the fourth linear conductors overlap each other, and the second and the third linear conductors overlap each other. The first, the second, the third and the fourth linear conductors are electrically connected to define a coil.
