Problems solved by technology

In practical applications, mainly the third harmonic will exceed the standard
Similarly, when the third harmonic energy of the radio frequency signal reaches the third resonance of the antenna, the energy of these higher harmonics will be radiated out, resulting in excessive radiation spurious

Abstract

The embodiment of the invention relates to the technical field of terminals, and discloses an antenna assembly, and terminal equipment. The terminal equipment comprises a radio frequency (RF) transceiver, an adjustment unit, and an antenna, wherein the RF transceiver is connected with the antenna through the adjustment unit, and is used for generating RF signals; the adjustment unit is used for changing the phase of higher harmonics carried by the RF signals; and the antenna is used for outputting the RF signals. The terminal equipment has the advantages that the phase of the higher harmonic derived from the RF signals can be changed, so that the intensity of the higher harmonics is relatively low when the intensity of the RF signals reaches the peak, and the problem of stray radiation canbe further reduced.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an antenna component and a terminal device. Background technique [0002] As a mandatory certification indicator for electronic equipment, radiation spurious is the most complicated and difficult problem in all certifications. Especially for the Global System for Mobile Communication (GSM) frequency band, because its own power is particularly high, it is easy to excite strong energy in an instant and cause the radiation of spurious harmonics to exceed the standard. In actual use, the third harmonic of GSM900 tends to exceed the standard, and the second or third harmonic of GSM 1800 exceeds the standard. [0003] For radio frequency signals, the transmitted signal will not only contain available signals (for example, GSM 900), but often also contain second (1800GHz) / third harmonic components (2700GHz). In practical applications, mainly the third harmonic will exceed th...
