Problems solved by technology

[0006] The above solutions either change part of the metal environment and affect the appearance; or too much damage the continuity of the metal frame and affect the robustness of the metal, which is not advisable; although the design of the anti-metal frame does not change the metal ring. The external appearance effect, but such a design takes up a large antenna space and holds relatively few frequency bands, especially does not cover any LTE frequency bands with broad application prospects

Abstract

The invention discloses an antenna for a smart phone with a metal frame that can cover seven frequency bands. The smartphone antenna divides the metal frame into several parts by setting a power-off gap and a short-circuit connector. The gap resonance between these separated parts of the metal frame and the metal floor can be used to cover low frequency bands such as GSM850 / 900, and its corresponding third resonance mode can be used to cover high frequency bands such as LTE2300 / 2500; At the same time, the separated metal frames can be regarded as distributed monopole branches to cover high-frequency bands such as GSM1800 / 1900, and the internal excitation unit itself can also generate signals that act on high-frequency bands such as GSM1800 / 1900 and UMTS2100. Resonant characteristics, so as to supplement the bandwidth of the metal frame radiation, to achieve the radiation effect of the metal frame antenna covering seven frequency bands under multi-standard. The resonance generated by the coupling metal ring is used to participate in the antenna radiation, which greatly shares the pressure of the resonance size that the printed antenna needs to bear. It is suitable for popularization and application in the field of terminal antenna technology.

Description

Technical field [0001] The invention relates to the technical field of terminal antennas, in particular to a smart phone antenna with a metal frame. Background technique [0002] With the rapid development of terminal communications, contemporary smart phones not only need to ensure functions such as call, download, and navigation, but also continue to pursue the experience effects that the appearance of the phone can bring to users. The smart phone introduces a metal frame, which makes the phone more sturdy and at the same time reflects the atmosphere of fashion. [0003] Mobile phone antennas are a key part of the wireless communication system. The mobile phone antennas required by the contemporary smart phone market not only need to meet the multi-frequency bands to expand the diversity of terminal communications, but also need to deal with more complex external metal environments. When the metal frame surrounds the mobile phone as a large metal part that cannot be ignored, it ...
