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 intelligent machine antenna with a metal frame, wherein the intelligent machine antenna can cover seven frequency bands. The intelligent machine antenna divides the metal frame into a plurality of parts through outage seams and short-circuited connectors. Seam resonance between parts of the separated metal frame and a metal floor can be used for covering low-frequency frequency bands such as GSM850/900, and a triple resonance mold corresponding to the seam resonance can be used for covering high-frequency frequency bands such as LTE2300/2500; meanwhile, the separated metal frame can be taken as distributed single-pole sub branches and used for covering high-frequency frequency bands such as GSM1800/1900, an internal excitation unit can also produce resonance characteristics acting on the high-frequency frequency bands such as GSM1800/1900 and UTMS2100, and accordingly the bandwidth of metal frame radiation is complemented, and the multi-system seven-frequency-band radiation effect of the antenna with the metal frame is achieved. Resonance produced by a couple metal ring is involved in antenna radiation, resonance size pressure needing to be borne by the printed antenna is shared to a great extent, and the antenna is suitable for being used and popularized in the technical field of terminal antennas.

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 communication, contemporary smartphones not only need to ensure functions such as calling, downloading, and navigation, but also continue to pursue the experience effect brought by the appearance of mobile phones to users. The smart phone introduces a metal frame, which makes the phone stronger and more stylish. [0003] The mobile phone antenna is a key part of the wireless communication system. The mobile phone antenna required by the contemporary smart phone market not only needs to meet multiple frequency bands to expand the diversity of terminal communication, but also needs to deal with a more complex external metal environment. When the metal frame surrounds the mobile phone as a large metal part that cannot be ignored, it will have a significant impact...
