Abstract

The present invention relates to an electronic device comprising: a circuit board installed inside the body of the electronic device and formed by alternately laminating conductive layers made of a conductive material and dielectric layers made of an insulative material; at least one patch antenna arranged on the circuit board; a core layer positioned at the center portion inside the circuit boardand made of one of the dielectric layers; a ground layer arranged on the lower portion of the core layer; and an EGB structure positioned inside the circuit board and shaped such that the upper and lower portions thereof are symmetric with each other with reference to the core layer, wherein the EGB structure can limit interference between operating frequency signals emitted from respective patchantennas.

Description

technical field [0001] The present invention relates to an electronic device having a circuit board on which an EBG structure is mounted. Background technique [0002] The electronic device can be realized in the form of a multimedia device (Multimedia player), which has composite functions of taking images or videos, playing music or video files, playing games, receiving broadcasts, etc., using various electronic components disposed inside the body. [0003] In addition, in recent years, with the expansion of multimedia functions of such electronic devices, antennas capable of transmitting and receiving wireless signals of various frequency bands are included inside. The antenna is connected to the wireless communication unit to transmit and receive signals of a specific frequency according to the control of the wireless communication unit. [0004] The antenna is mounted on the circuit substrate to perform the function of sending and receiving wireless signals. The circu...
