2. The low frequency director 132 acts to direct cross-polarized low frequency current to radiation while increasing gain and bandwidth, with more directors superimposed the higher the gain and the more concentrated the signal radiation direction.
3. The high, medium and low frequency radiating elements 133 all adopt actual physical dimensions obtained by a quarter wavelength (1/4 in) of the center frequency and a rate factor of 0.1-1.
4. The low-frequency component adopts a monopole mode to design a 45-degree cross polarization mode of two copper sheets and a low-frequency guide plate 132, so as to form good polarization and simultaneously bring bandwidth and gain into full play;
the medium-frequency oscillator adopts a 45-degree cross polarization design of a PCB-FR4 (dielectric constant 4.3-4.7) dipole symmetrical array mode, and a middle single copper sheet is used for forming coupling with the periphery, so that the bandwidth is better increased, and the medium-frequency gain and efficiency are improved;

5. The low-frequency combiner is designed by a coaxial line 50 omega transmission principle and is made of PCB-FR4 (dielectric constant is 4.3-4.7); because the medium frequency and the high frequency are too attenuated in the transmission line by using the conventional PCB-FR4 design, the parameter requirement cannot be met, and therefore, the medium frequency and high frequency line combiner is designed by adopting a PTFE (dielectric constant 2-3) high frequency plate material through a coaxial line 50 omega transmission principle; meanwhile, the combiner of the medium-frequency and high-frequency lines is designed in an array mode, so that the energy of 3 arrays of array antennas at two sides is concentrated and summarized, and the gain is improved; designing a basic formula for improving gain between two arrays:
d/lambda, D represents distance, lambda represents frequency wavelength, and the minimum value starts to debug from the ratio of one quarter wavelength to the wavelength of 0.25 to achieve the best effect;

the half-power gain is 2.15dBi, the existing half-wave oscillators are arranged in the vertical direction to form a constant-amplitude in-phase binary linear array, and the array factor directional diagram is as follows:

f(θ)＝F(θ)*fα(θ)
the antenna 3 array gain is:
the gain was calculated to be optimal at 0.95A.
6. The reflecting plate 11 enables all the frequencies to be concentrated towards the direction point of one surface, and collects and transmits signal radiation energy farther; while the distance of the reflector plate 11 (element) from the radiating element of the antenna 3 can be adjusted from one sixteenth to one quarter wavelength, resulting in an optimally optimized design.
