Abstract

The invention provides a novel LTE antenna with an all-metal frame. The novel LTE antenna comprises a PCB (Printed Circuit Board), an outer metal frame and an antenna part, wherein the outer metal frame is arranged around the PCB and is connected with the PCB, one end of the PCB is provided with a clean area, the antenna part is arranged at the clean area, the antenna part comprises a feed part and a radiation part connected with the feed part, the radiation part is further connected with the outer metal frame to form a radiation loop and to generate first high frequency resonance, a first slot part and a second slot part are respectively arranged between two side edges of the PCB adjacent to the end provided with the antenna part and the outer metal frame, the first slot part and the second slot part are respectively communicated with the clean area, the first slot part generates second high frequency resonance, and the second slot part generates first low frequency resonance. The novel LTE antenna makes full use of the slots between the metal frame and the PCB to carry out radiation and further realize broadband characteristics, moreover, no gaps are arranged on the metal frame, so the novel LTE antenna has property of attractive effects.

Description

technical field [0001] The invention relates to the technical field of mobile phone antenna design, in particular to a novel LTE antenna with an all-metal frame. [0002] Background technique [0003] Miniaturized multi-band built-in antennas have always been the development direction of handheld communication terminal antennas. Existing antenna forms include multi-frequency monopole antenna (monopole antenna), single loop or dual loop antenna (single loop and dual loop antenna), inverted folded antenna (IFA), and planar inverted folded antenna (PIFA). These antenna types have their own conditions and performance in different handheld communication terminal environments, and different antenna forms can be selected according to different requirements. [0004] Usually mobile terminal equipment includes GSM850 / 900, DCS, PCS, UMTS, and its frequency range is 0.824GHz-0.96GHz, 1.71GHz-2.17GHz. With the continuous development of LTE technology, 3.5GHz and 4GHz frequency bands ...
