Problems solved by technology

In fact, this requirement also limits the reduction of the electrical size of the antenna, because the metal layer is also a necessary part of the antenna. If it is not compact enough and the size is large, it is difficult to reduce the size of the antenna

Embodiment Construction

[0016] The embodiment of the present invention provides a mobile phone antenna and a mobile phone, based on the principle of the echo characteristics of the double negative medium to reduce the resonant frequency of the antenna, so as to achieve the purpose of reducing the size of the mobile phone antenna. The mobile phone antenna adds a double-negative material metal layer on the metal floor under the dielectric substrate. The metal layer adopts a compact structure, and the size of each unit can be much smaller than the working wavelength of the antenna. The double negative material resonant cavity is formed between the double negative material, the conductive patch and the dielectric substrate. The double negative material resonant cavity plays a role of phase compensation for the inherent double positive material resonant cavity of the dielectric substrate, and the double negative material (DNG) resonant The cavity and the double positive material (DPS) resonant cavity are a...

Abstract

The invention provides a cell phone antenna and a cell phone, wherein the cell phone antenna comprises a dielectric substrate, a rectangular conductive patch which is arranged on one side of the dielectric substrate and a metal floor which is arranged on the other side of the dielectric substrate, wherein the metal floor is provided with double negative material, and a double negative material resonant cavity is formed by the double negative material, the rectangular conductive patch and the dielectric substrate, and the double negative material resonant cavity is along the width which is less than the distance between two radiating sides of the rectangular conductive patch and is parallel to the dielectric substrate, the interface of the double negative material resonant cavity and a double positive material resonant cavity which is fixedly provided by the dielectric substrate is parallel to the two radiating sides of the rectangular conductive patch and is crossed with two non-radiating sides of the rectangular conductive patch. The cell phone antenna can greatly reduce the electric size of an antenna under the premise of guaranteeing necessary radiation efficiency and transmission gain.

Description

technical field [0001] The invention relates to the design field of mobile phone antennas, in particular to a mobile phone antenna and a mobile phone. Background technique [0002] The current mobile phone is developing in the direction of multi-function, miniaturization, and low radiation loss. The antenna of the mobile phone directly determines the performance of the mobile phone to radiate and receive electromagnetic wave signals, which affects the communication capability of the mobile phone. The quality of the mobile phone antenna design may determine the mobile phone in the market. in the living space. How to minimize the electrical size of the antenna on the premise of maintaining the necessary radiation efficiency and gain of the mobile phone antenna will be a meaningful problem. [0003] There are mainly two existing methods for reducing the electrical size of the antenna: first, for the vibrator antenna, loading techniques are mainly used to reduce the electrical ...
