Antenna device of handheld terminal

Abstract

The invention discloses an antenna device of a handheld terminal, comprising a metal decorating piece and a metal decorating strip and also comprising a PCB (printed circuit board) and an antenna bracket, wherein the metal decorating piece is arranged at the top part of handheld terminal equipment; the metal decorating strip is arranged at the bottom part of the handheld terminal equipment; the PCB is attached at the bottom surface of the metal decorating piece; the antenna bracket is arranged in the handheld terminal equipment; an energy feed source is connected onto the PCB and is electrically connected with an antenna pattern arranged on the antenna bracket; the antenna pattern is electrically connected with the metal decorating piece which is electrically connected with a grounding surface of the PCB by a metal connecting piece; and the grounding surface of the PCB is electrically connected with a main grounding surface of the handheld terminal equipment by a metal connecting piece. In the antenna device, not only is the metal texture of the handheld terminal equipment such as a mobile phone and a computer and the like ensured, but also the wireless performance of the whole equipment is improved, and the multiband working requirement of the handheld terminal equipment is met.

Description

technical field [0001] The present invention relates to an antenna device, in particular to an antenna device on a hand-held terminal, such as a mobile phone, a tablet computer and the like. Background technique [0002] The vigorous development of wireless communication technology has led to more and more information sub-modules on the same terminal system. For example, current mobile phones, especially smart phone systems, are generally equipped with sub-communication modules such as GSM, DCS, PCS, UTMS, BT / WIFI and GPS. The increase of these information sub-modules will inevitably lead to the expansion of the antenna frequency band and the increase of the complexity of the antenna structure. In order to win the favor of consumers and take the lead in the increasingly competitive consumer electronics market, mobile phones and other products are developing in the direction of thinner and stronger metal textures, and thinner and stronger metal texture handheld terminal devic...

Problems solved by technology

In short, it can be seen from the basic principles of antennas that these antenna forms are easily limited by height and area, and when used as lower antennas, they are greatly affected by human hands, and for the case of large metals in a very short distance, the Bandwidth and efficiency performance are hard to meet
