Embodiment Construction

[0025] As mentioned in the background, existing antennas generally use In 2 o 3 (ITO) or SnO 2 (FTO) prepared. However, the resistance of ITO and FTO materials is large, and the square resistance is about 1.5Ω / □, which leads to low radiation efficiency of the antenna. Moreover, the existing antennas made of ITO or FTO are relatively thick, resulting in a light transmission efficiency between 40% and 80%, which is relatively low.

[0026] In order to solve the above problems, an embodiment of the present application provides an antenna for communication electronic equipment, the antenna includes:

[0027] A transparent conductive film with a preset structure for sending and receiving signals;

[0028] Wherein, the transparent conductive film can pass light in the visible wavelength range, and the square resistance of the transparent conductive film is less than 1.5Ω / □.

[0029] The antenna of the present invention is made of a transparent conductive film, which can pass li...

Abstract

The invention discloses an antenna and communication electronic equipment. The antenna comprises a transparent conductive film in a preset structure, wherein the transparent conductive film is used for receiving and transmitting a signal and can allow visible light to pass, and the sheet resistance of the transparent conductive film is less than 1.5 ohm per square. The transparent conductive film can allow the visible light to pass, and is better in transparency. The antenna can be disposed on the external surface of the communication electronic equipment, and does not affect the appearance of the equipment. Meanwhile, the antenna is suitable for transparent communication electronic equipment or locally-transparent communication electronic equipment because the transparent conductive film is better in transparency. Moreover, the sheet resistance of the transparent conductive film is less than 1.5 ohm per square, thereby enabling the resistance of the antenna to be reduced on the condition that the size is the same, reducing the energy consumption, and improving the radiation efficiency of the antenna. Therefore, the communication electronic equipment with the antenna is high in signal radiation efficiency. Moreover, the thin film transparent antenna is employed, so the thickness is smaller, and the antenna is suitable for the manufacturing of ultra-thin type portable communication electronic equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to an antenna and communication electronic equipment. Background technique [0002] The radio frequency signal power output by the radio transmitter is sent to the antenna through the feeder, and is radiated by the antenna in the form of electromagnetic waves. After the electromagnetic wave reaches the receiving location, it is followed by the antenna and sent to the radio receiver through the feeder. It can be seen that the antenna is an important radio device used by communication equipment to transmit and receive electromagnetic waves. Without an antenna, there is no radio communication. [0003] Transparent antenna is a kind of antenna commonly used in today's communication electronic equipment, generally using In 2 o 3 (ITO) or SnO 2 (FTO) prepared. However, conventional transparent antennas have low radiation efficiency. Contents of the invention ...
