Problems solved by technology

Although the radiation of the antenna to the human body is reduced by reconfiguring the pattern, it cannot cover the GSM900 frequency band, and its application range is narrow. Therefore, designing a miniaturized antenna with both frequency and pattern reconfigurable functions is of great importance to increase the practicability of the antenna. Significance

The green, mixed and reconfigurable mobile phone antenna comprises a first dielectric-slab, a straight active oscillator, snake-shaped active oscillators, an upper passive oscillator, a front passive oscillator and a rear passive oscillator. The upper passive oscillator is printed on the upper surface of the first dielectric-slab, the straight active oscillator, the front passive oscillator and the rear passive oscillator which are mutually parallel are printed on the lower surface of the first dielectric-slab, the front passive oscillator and the rear passive oscillator are located on the front side of the straight active oscillator and the rear side of the straight active oscillator respectively, the snake-shaped active oscillators comprise the first snake-shaped active oscillator and the second snake-shaped active oscillator, the first snake-shaped active oscillator and the second snake-shaped active oscillator are located at the left end of the straight active oscillator and the right end of the straight active oscillator respectively and are centrally symmetrical about the straight active oscillator, and the straight active oscillator is connected with a feeder. The green, mixed and reconfigurable mobile phone antenna can be switched between an all-direction state and a directional state according to communication states of a mobile phone and realize green communication, the SAR value on a human body of the antenna is reduced, the working frequency band can be switched according to communication requirements, therefore, the working bandwidth of the antenna is expanded, and the frequency and the direction diagram can be reconfigured at the same time.

Description

technical field [0001] The invention relates to an antenna, specifically a mobile phone antenna. Background technique [0002] In recent years, with the rapid development of wireless communication technology, the role of wireless communication in people's lives has become more and more prominent. As the fastest growing mobile terminal in the wireless communication industry, mobile phones have become an indispensable part of people's daily life. At the same time, with the improvement of the quality of life, people's health awareness is gradually enhanced, and the electromagnetic radiation produced by mobile phones has gradually attracted people's attention. How to effectively reduce the Specific Absorption Rate (Specific Absorption Rate) value of mobile phones and reduce the impact of mobile phone radiation electromagnetic waves on the human body has become an urgent problem to be solved. Mobile phone antennas are divided into built-in and external antennas according to thei...
