Mobile phone antenna with narrow frame

Abstract

The invention discloses a mobile phone antenna with a narrow frame. The mobile phone antenna comprises a substrate, a metal grounding plate, a parasitic ground structure, a vertical rectangular metalstructure, an antenna rectangular clearance area and a feed port, wherein the metal grounding plate and the parasitic ground structure are arranged on the lower surface of the substrate; the verticalrectangular metal structure is arranged on the edge of the substrate; the antenna rectangular clearance area is arranged on the upper surface of the substrate and corresponds to the frame; and the feed port penetrates the upper surface and the lower surface of the substrate. The antenna has characteristics that 7 commonly-used communication frequency bands can be covered and an LTE700 frequency band can be covered too; and the structure is simple and compact and the antenna is easy to process.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a mobile phone antenna with a narrow frame covering eight frequency bands including LTE700. Background technique [0002] With the rapid development of wireless communication technology, people have put forward higher requirements on the performance and appearance of mobile phones. In order to meet the needs of users, mobile phone manufacturers have also launched a series of large-screen mobile phones. Compared with ordinary mobile phones, large-screen mobile phones have the characteristics of narrow bezels and high screen-to-body ratio, which can achieve better visual effects, so they are more attractive to users. [0003] However, the introduction of large-screen mobile phones means that mobile phone antennas need to be designed in a narrower space to cover the required 2G / 3G / 4G frequency bands, which puts higher requirements on the design of mobile phone antennas.
