Problems solved by technology

This shielding effect will prevent high-frequency noise from penetrating the conductive layer to radiate along the direction perpendicular to the conductive layer, but instead will concentrate high-frequency noise on the edge of the conductive layer and radiate out.
[0005] In this way, the wireless sensitivity of the antennas disposed adjacent to the edge of the conductive layer will be greatly affected.
Since wireless reception capability has a great influence on the quality of electronic communication devices, poor reception capability is undesirable for designers

[0056] Please refer to Figure 6 , which represents a top view of the metal thin film key of the electronic communication device according to the second embodiment of the present invention. The difference between the second embodiment and the first embodiment lies in the shape of the electrostatic protection layer 603 and the relative positional relationship between the antenna feeding point (feed-in hole) 1021 and the electrostatic protection layer 603, and the rest are the same as the first embodiment. The same reference numerals are used and will not be described again.

[0057] The electrostatic protection layer 603 has a first edge 6031 and a second edge 6032, wherein the first edge 6031 and the second edge 6032 are separated by at least a predetermined distance L 5 and L 6 The distance of is adjacent to the antenna feed point 1021. That is, the distance between the first edge 6031 and the second edge 6032 and the antenna feeding point 1021 is at least L 5 and L 6 ab...

Abstract

The invention consists of a printed circuit board, an antenna component, an insulation layer and an electrostatic protection layer. The antenna component is mounted at the side near the printed circuit used to transmit and receive the wireless signal sent by printed circuit. The insulation layer is located on the printed circuit board, on which an electrostatic protection layer is mounted. The electrostatic protection layer has at least one hollow out area whose location corresponds to the area of printed circuit board generating high frequency noise. The hollow out area radiates out the high frequency noise generated from area of printed circuit board generating high frequency noise to reduce interference of noise to antenna.

Description

technical field [0001] The present invention relates to a wireless electronic communication device, and more particularly to a wireless electronic communication device that reduces noise interference of antenna elements. Background technique [0002] For wireless electronic communication devices, such as handheld mobile phones, most of the external static electricity comes from the fingers of the human body, especially in a dry and cold environment, the human body is more likely to be charged with static electricity. When a user with a charged finger uses a button, the static electricity will be transmitted from the fingertip to the touched button in an instant. Therefore, the interference of electrostatic discharge (ESD) is harmful to the electronic components in the wireless electronic communication device. [0003] In traditional wireless electronic communication devices, in order to prevent external static interference, a grounded conductive layer is provided under the ...
