Embodiment Construction
[0038] The present invention will be described in further detail below with reference to the embodiments of the drawings:
[0039] The design process of the ultra-wideband planar phased array mainly includes: the analysis and design of the antenna unit of each frequency band; the design of the liquid crystal phase shifter unit of each frequency band; the block array design of the multi-band antenna unit array. First, complete the design of the antenna unit and the liquid crystal phase shifter unit according to the different technical indicators of each frequency band array, and then complete the design of the ultra-wideband planar array unit according to the antenna unit and the liquid crystal phase shifter unit, ensuring that the ultra-wideband planar array unit of each frequency band In the case of coplanarity, the impedance matching method is adopted to select the working frequency band to complete the overall design of the four frequency band array units. The design of the ar...
