Multi-frequency multi-mode reconfigurable mobile phone antenna

Abstract

The invention relates to a multi-frequency multi-mode reconfigurable mobile phone antennas, which comprises a metallic conductor part, a carrier for bearing the metallic conductor part, and a radio frequency switch, wherein the metallic conductor part comprises an antenna main body and a feeding point and a grounded point below the antenna main body; the feeding point and the grounded point are connected with a feeding point and a GND of a main board of a mobile communication terminal device respectively; the antenna main body comprises five conductor branches including a reversed L-shaped conductor part with width variation, a non isometric stretched conductor part, a thread conductor part which is bent for three times, a short circuit tuning branch and an inductive coupling reversed L-shaped conductor part; the radio frequency switch is arranged in the left center of the inductive coupling reversed L-shaped conductor part; and the antenna main body is bent and folded through five fold lines in turn to form a solid structure. The antenna can meet the radio communication requirement of systems such as EGSM, GPS, DCS, PCS, TD-SCDMA, TD-LTE, Bluetooth, WiMAX2.5, IMT-Advanced, WLAN5.2, WiMAX5.8 and the like, and simultaneously has the advantages of low profile, small volume and high gain.

Description

technical field [0001] The invention relates to an antenna in the field of communication technology, in particular to a multi-frequency and multi-mode reconfigurable mobile phone antenna. Background technique [0002] With the rapid development of VLSI and high-performance battery technology, mobile communication terminals integrate more and more functions. This requires the mobile communication terminal antenna to have the ability to work in multiple frequency bands, so as to meet the needs of 2G, 3G, and future 4G mobile communication, satellite communication, short-distance communication and broadband access communication. And the antenna also needs to meet the requirement of no mutual coupling between frequency bands under the condition of miniaturization and built-in type. [0003] The communication technologies that will be integrated into the same mobile terminal in the future include: EGSM (880-960MHz), GPS (1575±3Hz), DCS (1710-1880MHz), PCS (1850-1990MHz), TD-SCDM...

AI Technical Summary

Problems solved by technology

This antenna system cannot cover frequency bands such as TD-LTE and IMT-Advanced. In addition, since multiple antennas are used to cover nine frequency bands, it has a large volume and strong mutual coupling, which does not meet the requirements of miniaturization and built-in
