Problems solved by technology

For most types of antennas, when the antenna is in the working state, the antenna feed point has a strong signal distribution. When using the terminal, if the position where the human hand holds the terminal or other external conductors such as the head touch The location is exactly at the feed point of the antenna, and human hands will cause a large loss to the antenna, reducing the communication performance of the antenna

Embodiment Construction

[0032] In order for those skilled in the art to better understand the technical solutions of the present invention, a method and system for reducing antenna loss provided by the present invention, an antenna device and a mobile terminal are further described in detail below with reference to the drawings and specific embodiments.

[0033] The antennas in the embodiments of the present invention include but are not limited to symmetrical antennas such as symmetrical monopole antennas and loop antennas. When the antenna device is working, its antenna feed point is used to transmit and receive radio frequency signals. If the antenna feed point or antenna feed The area around the point is covered or contacted by an external conductor, which will greatly absorb the radiated signal of the antenna device and reduce the communication performance of the antenna. Therefore, the positions of the antenna ground point and the antenna feed point of the antenna in the antenna device are switc...

Abstract

The invention discloses a method and system for reducing antenna loss, an antenna device and a mobile terminal. The method for reducing the antenna loss comprises the steps of detecting a contact position of an external conductor on the terminal; and setting an antenna access point, near to the contact position, in two antenna access points arranged at different positions of the terminal as an antenna grounding point and the antenna access point far away from the contact position as an antenna feeding point. Through the mode, the influence of the external conductor on a radio frequency signal of an antenna can be reduced, the antenna loss is reduced, and the antenna performance is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a method and system for reducing antenna loss, an antenna device and a mobile terminal. Background technique [0002] Antennas are transducers designed to send and / or receive radio, television, microwave, telephone and radar signals, ie antennas transform electric currents of a certain frequency into electromagnetic waves and vice versa. Physically, an antenna is one or more electrically conductive devices arranged to generate a radiated electromagnetic field in response to an applied alternating voltage and associated alternating current, or the device may be placed in an electromagnetic field such that the electromagnetic field will pass through the antenna It induces an alternating current and a voltage across its terminals. [0003] As a sending and / or receiving device of a wireless signal of a terminal, the antenna needs to have a strong performance of transmitting...
