Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1: the utility model includes a metal reflective barrel 1, a vibrator 2, a feeder 4, a bracket 5 and a fixing bolt 3, the metal reflective barrel 1 is placed horizontally, the barrel wall of the metal reflective barrel 1 is equipped with a bracket 5, and the metal reflective barrel 1. The side on which the bracket 5 is installed is the bottom surface. The side of the metal reflector 1 is provided with a through hole. The fixing bolt 3 passes through the through hole of the metal reflector 1 and is fixedly connected. The center of the fix bolt 3 is provided with a through hole, and the feeder 4 passes through Through the through hole in the center of the fixing bolt 3 and fixedly connected, the vibrator 2 is a parallelogram, and one end of the vibrator 2 is welded to the end of the feeder 4 and placed in the metal reflective barrel 1 . The radius of metal reflective barrel 1 is 60mm-110mm, preferably 65mm; the depth of metal reflective barrel 1 is 150mm-180mm, preferably 160mm; the circumference of vibrator 2 is 120mm-240mm, preferably 130mm. The length is 30mm-60mm, preferably 32.5mm. the

As shown in Figure 1: the resonant frequency of the vibrator 2 is determined by the total length, and can be designed according to the center frequency required by the user. If it is 6 channels, the center frequency is 2.437GHz, and the wavelength in vacuum is 0.12310 meters (λ= C/f=299792458/2437000000). Let the dielectric constant of air be 1. Then the total length corresponding to the resonant frequency 2.437GHz of vibrator 2 is 4λ/2=0.1231m=123.1mm, and the length of each side is 30.775mm; if channel 1 is selected, the center frequency is 2.412Ghz, and the length of each side is 31.095mm; if channel 11 is selected , the center frequency is 2.462Ghz, and each side is 30.34mm long. The side length of the vibrator 2 can be changed according to different requirements. The function of the metal reflective bucket 1 is to focus the electromagnetic wave to the receiving position of the vibrator 2 like a solar cooker, and at the same time project the electromagnetic wave emitted by the focus point. the
