High gain rectangular oscillator antenna

The utility model discloses a high gain rectangular oscillator antenna. By the excellent structure design, by applying the semiconductors to the oscillator sheets creatively and combining the semiconductor structures with the oscillators, by the continuous experiment, by designing the rectangular metal oscillator sheets and arranging the semiconductor rings at the peripheries of the metal oscillator sheets, and by the structure design on the metal oscillator sheets, the flow direction length and speed of a radiation signal flow on the metal oscillator sheets are improved greatly. By the simulation of a lot of computer software, the working frequency band of the high gain rectangular oscillator antenna reaches 3000 MHz, totally satisfying the frequency requirement standard of a 4G network. The relative bandwidth of the high gain rectangular oscillator antenna reaches 65.9%, and the high gain rectangular oscillator antenna possesses the characteristics of good gain, front-to-back ratio and cross polarization ratio.
