Embodiment 1
[0026] like figure 1 , figure 2 , image 3 as shown, figure 1 It is a structural perspective view of the broadband dual-polarized solar cell antenna; figure 2 It is a structural top view of the broadband dual-polarized solar cell antenna; image 3 It is a side sectional view of the broadband dual-polarized solar cell antenna.
[0027] The broadband dual-polarized solar cell antenna includes an antenna oscillator layer, an isolation layer 4, a solar cell sheet layer, and an antenna base 7 arranged in sequence from top to bottom. The antenna vibrator layer is connected to the antenna base 7 and the coaxial radio frequency connector 8 through a metal post feeding structure, the solar battery sheet is arranged on the antenna base 7, and the isolation layer 4 is arranged on the Between the antenna oscillator layer and the solar cell sheet layer.
[0028] The antenna element layer includes a dual-polarization element 1, a parasitic patch 2, and a substrate 3, the dual-polari...
Embodiment 2
[0046] like Figure 4 , Figure 5 , Image 6 as shown, Figure 4 is a structural perspective view of the antenna array; Figure 5 is a structural top view of the antenna array; Image 6 It is a schematic diagram of the structural positions of adjacent dual-polarized solar cell antennas. The antenna array of the present invention is formed by several dual-polarized solar cell antennas in a square grid array. The vertically polarized oscillator 20 and the horizontally polarized oscillator 21 are arranged periodically, and the metal pillar feed structure is located in the middle of the vertically polarized oscillator 20 and the horizontally polarized oscillator 21 in a "hollow bow tie" shape .
[0047] In order to improve the performance of the antenna, a number of parasitic oscillators 22 are arranged around the periphery of the antenna array, and the outer terminals of the parasitic oscillators 22 are connected to the parasitic grounding metal posts 23 .
[0048] The sol...
