Problems solved by technology

However, the current mobile phone industry is developing towards large screen, ultra-thin, and multi-functional. This development trend leads to less and less space in the mobile phone casing for antenna design, and the radiation environment of mobile phone antennas is becoming more and more complicated.
The casing of a conventional mobile phone is equipped with basic components such as a USB interface, a miniature microphone, a speaker, a battery, and a motor. The performance of the mobile phone, resulting in a decrease in antenna radiated power

Abstract

The invention discloses a cell phone 4G double-LOOP structure antenna belonging to the cell phone antenna technology field. The cell phone 4G double-LOOP structure antenna comprising a signal feed point, a first feed grounding point, a second feed grounding point, a first antenna wiring, a second antenna wiring, a first high frequency arm, a high frequency coupling arm, a second high frequency arm, and a low frequency arm. The first antenna wiring, the signal feed point, and the first feed grounding point are used to form a first LOOP structure. One end of the first antenna wiring is connected with the signal feed point, and the other end is connected with the first feed grounding point. The second antenna wiring, the signal feed point, and the second feed grounding point can be used to form a second LOOP structure, and one end of the second antenna wiring is connected with the signal feed point, and the other end is connected with the second feed grounding point. The first high frequency arm and the high frequency coupling arm are respectively connected with the first LOOP structure, the second high frequency arm and the low frequency arm are respectively connected with the second LOOP structure. The cell phone 4G double-LOOP structure antenna is advantageous in that the good performance of the antenna can be provided in the severe radiation environment, and the SAR risks can be reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of mobile phone antennas, and in particular relates to a mobile phone 4G dual LOOP (loop) structure antenna. Background technique [0002] Antenna is a metal device used to transmit or receive radio waves that can resonate with signals. The length of the antenna is proportional to the wavelength, the higher the frequency, the shorter the wavelength and the smaller the antenna size. The frequency of the existing mobile phone is very high, and the antenna is small, so it can be directly etched on the PCB board (printed circuit board) to meet the demand for miniaturization of the mobile terminal. However, the current mobile phone industry is developing towards large screen, ultra-thin, and multi-functional. This development trend leads to less and less space in the mobile phone casing for antenna design, and the radiation environment of mobile phone antennas is becoming more and more complex. The casing of a ...
