Problems solved by technology

In order to increase the inductance, the number of turns of the coil needs to be increased, however, since the size of electronic components is in the trend of miniaturization, the number of turns cannot be increased blindly
In addition, in the case of a main antenna as an example of a coil electronic component, since it is constituted by a loop antenna in the form of an air-core coil, it is necessary to increase the number of turns of the coil in order to increase the inductance. , thus, resulting in an increase in the characteristic of the DC resistance (Rdc)
In addition, the sub (sub) antenna will also form a magnetic field mainly along the direction perpendicular to the coil, so there is a limitation in increasing the recognition angle
[0003] In this case, the following Patent Document 1 discloses an electronic component in which a plurality of coils are wound on a magnetic core laminated with a plurality of thin metal plates so that the respective coils are connected in parallel. The problem of diversification of the characteristics of the magnetic core

Abstract

The invention discloses a coil electronic component and antenna, wherein the electronic component includes a main body having a magnetic characteristic and a coil arranged on the external surface of the main body, the main body contains a plurality of sheets, and the uppermost sheet and the lowermost sheet among the sheets are protective sheets; and the antenna contains the main body in the coil electronic component as a core part and contains the coil in the coil electronic component as a coil part,, and is arranged in the position of a main antenna or the position of a sub-antenna.

Description

technical field [0001] The present disclosure relates to a coil electronic component and an antenna, and more particularly to a coil electronic component and an antenna that contain a magnetic material in a main body, and the main body includes a plurality of sheets, and has a structure in which a coil is wound on an outer surface of the main body . Background technique [0002] Generally, if a current flows through a coil, a magnetic field is generated in a direction perpendicular to the coil, thereby having an inductance. In order to increase the inductance, the number of turns of the coil needs to be increased, however, since the size of electronic components is in the trend of miniaturization, the number of turns cannot be increased blindly. In addition, in the case of a main antenna as an example of a coil electronic component, since it is constituted by a loop antenna in the form of an air-core coil, it is necessary to increase the number of turns of the coil in order...
