WWAN antenna suitable for all-metal rear shell of notebook computer

Abstract

The invention discloses a WWAN antenna suitable for an all-metal rear shell of a notebook computer, the WWAN antenna comprises a notebook computer body, and a WWAN Main antenna, a WWAN MIMO 1 antenna, a WWAN Aux antenna and a WWAN MIMO2 antenna which are arranged on the notebook computer body, the WWAN Main antenna and the WWAN Aux antenna adopt the same structure, and the WWAN MIMO 1 antenna and the WWAN MIMO2 antenna adopt the same structure; the WWAN antenna suitable for the all-metal rear shell of the notebook computer further comprises a metal C shell, a metal D shell, first metal C shell antenna plastic, second metal C shell antenna plastic, a metal D shell antenna plastic window, a C shell WWAN MIMO2 metal ring and a C shell WWAN Aux metal ring. The WWAN antenna suitable for the all-metal rear shell of the notebook computer ensures that the all-metal rear shell notebook computer meets the network access efficiency in a power-on state through terminal wireless communication, induces human body approaching through a P sensor, and adjusts the module output power in time so as to ensure human body radiation safety.

Description

technical field [0001] The invention relates to the technical field, in particular to a WWAN antenna suitable for an all-metal rear shell of a notebook computer. Background technique [0002] Business notebooks usually need to be connected to the Internet at any time through the base station, so they need to be equipped with multiple WWAN antennas. At the same time, in order to ensure the quality of the network, the common solution is to match the machine with 2 WWAN (617MHz to 5GHz) and 2 LTE (1700MHz to 5GHz) antennas to form MIMO. Due to the need to support LTE low frequency 617MHz, the 2 WWAN antennas require a larger physical size to perform effectively. Therefore, the commonly used solution is to combine four WWAN antennas in pairs and place them at the frame of the C&D shell of the machine. There are two design difficulties that follow: [0003] 1. At present, more and more notebook computers use an all-metal back cover (D shell) for the purpose of thinner body, st...

Problems solved by technology

At the same time, due to the existence of the metal bracket of the notebook C shell keyboard, it is very challenging for the WWAN antenna to achieve performance only through the compact plastic window of the C&D shell in an environment surrounded by all metal;

[0004] 2. Since the four WWAN antennas are placed on the frame of the C&D shell, the palm of the human body will touch or be very close to the WWAN antenna when using the keyboard, posing potential radiation safety hazards

In a very compact frame area, if you want to add the design and connection of the P-sensor at the same time, while ensuring the performance of the antenna, you must make the P-sensor work and cover the sensing distance in the six directions of front, rear, left, right, up, and down, and you will face a greater challenge. challenge
