Abstract

The embodiment of the invention provides terminal equipment, and belongs to the technical field of communication. The terminal equipment comprises a floor and an antenna, and the antenna comprises a first radiation arm, a second radiation arm and a connecting piece; the first end of the first radiation arm is electrically connected with the first end of the second radiation arm through the connecting piece; a first excitation source is connected between the first end of the first radiation arm and the first end of the second radiation arm, and the antenna works in a first mode under the actionof the first excitation source; a second excitation source is connected between the connecting piece and the floor, and the antenna works in a second mode under the action of the second excitation source; the first mode is orthogonal to the second mode. In the embodiment of the invention, two modes are excited through the first excitation source and the second excitation source, and the two modesare orthogonal, so that the effects of high antenna port isolation and small spatial correlation can be achieved, antenna decoupling is realized without introducing an additional structure or circuit, and the performance of the whole communication system is improved.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communications, and in particular to a terminal device. Background technique [0002] In order to meet the requirements of various communication services, more and more antennas need to be accommodated in the terminal equipment, and the distance between the antennas is getting smaller and smaller, and the working frequency bands of these antennas are the same, such as multiple input multiple output (MIMO ) antenna, or very close, such as Long Term Evolution (LTE) Band40 (2.3GHz–2.4GHz) and wireless network (Wireless Fidelity, Wi-Fi) 2.4GHz (2.4GHz–2.484GHz), resulting in There will be strong electromagnetic coupling. [0003] Antenna coupling will lead to poor port isolation between the two antennas, and will also reduce antenna efficiency, because the energy emitted by one antenna will flow into the port of the other antenna to be absorbed by the load due to insufficient port...
