Abstract

The invention provides a novel bandwidth-enhanced LTE (long term evolution) metal frame antenna, which comprises a printed circuit board of a hand-held terminal, a metal outer frame connected with an edge part of the PCB, an antenna part and an electrical part connected with the antenna part, wherein the antenna part is positioned in a clearance area arranged on the PCB and is connected with the PCB; the antenna part mainly comprises the metal outer frame, a feed part, an earthing part, a loop radiation part and an earthing point electrical connecting part; the electrical part mainly comprises an electrical connector for connecting and disconnecting radio-frequency signals, and an electrical reactance device; a radio frequency earthing end is arranged inside the electrical connector and is used for being connected with the PCB to be earthed; and the electrical connector is connected with a mobile terminal signal, so as to control connection and disconnection of the electrical connector. With the adoption of the novel bandwidth-enhanced LTE metal frame antenna, by effectively utilizing parts of the metal outer frame and adding the electrical connector, and through controlling the connection and disconnection of the electrical connector, the bandwidth enhancing effect is realized, so that multiple frequency ranges of a GSM (global system for mobile communication), a UMTS (universal mobile telecommunications system) and the LTE can be covered.

Description

technical field [0001] The invention relates to the technical field of mobile phone antenna design, in particular to a novel LTE metal frame antenna with enhanced bandwidth. [0002] Background technique [0003] Miniaturized multi-band built-in antennas have always been the development direction of handheld communication terminal antennas. The 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. 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 hav...
