Abstract

The invention discloses a small broadband reconstruction smart phone antenna. By the adoption of the small broadband reconstruction smart phone antenna, the problems that in the prior art, a smart phone antenna which is small in size, low in profile and capable of achieving multi-frequency broadband working is hard to design in an given environment, and technology development requirements can not be met are mainly solved. The small broadband reconstruction smart phone antenna comprises a shell, a medium plate arranged in the shell, a metal land arranged on one surface of the medium plate, second bending metal strip sets and first bending metal strip sets, wherein the second bending metal strip sets are all arranged on the other surface of the medium plate, the first metal strip sets are connected with feeding points (1), and the first bending metal strip sets and the second bending metal strip sets are all composed of more than one metal strip, chip diodes, chip inductors and chip capacitors, wherein the chip device diodes, the chip inductors and the chip capacitors are connected among the metal strips. According to the scheme, the small broadband reconstruction smart phone antenna achieves the goals of being small, capable of covering eight working frequency bands and high in cost performance, and has high practical value and promotional value.

Description

technical field

[0001] The invention relates to a mobile phone antenna, in particular to a miniaturized broadband reconstruction smart phone antenna. Background technique

[0002] With the rapid development of wireless communication technology, smart phones have gained more and more attention. At the same time, the antenna as a "window" for communication between mobile phones and the outside world has received more and more attention from the industry. Today, the 4G era has arrived, and designing a miniaturized smartphone antenna that can cover eight frequency bands has become a top priority for major communication companies.

[0003] At present, the main difficulty faced by smartphone antenna design is: how to design a smartphone antenna with small size, low profile, and multi-band broadband operation in a given environment. The current mainstream mobile phone integrates many electronic components on the circuit board to meet the multi-functional requirements, which furthe...

Embodiment

[0020] In order to solve the problems existing in the prior art that it is difficult to design a smart phone antenna with a small size, low profile, and multi-band broadband operation in a given environment, which cannot meet the needs of technological development, such as figure 1 As shown, the present invention discloses a miniaturized broadband reconfigurable smart phone antenna, including a casing. In the present invention, a plexiglass casing is selected and arranged inside the casing. A dielectric plate with a metal ground on one surface is arranged on the other surface of the dielectric plate. , a first bent metal strip group and a second bent metal strip group composed of more than one metal strip and patch diodes, chip inductors and chip capacitors connected between the metal strips.

[0021] Such as figure 1 As shown, the first bent metal strip group consists of the first metal strip 25, the second metal strip 26, the third metal strip 27, the fourth metal strip 28, ...
