Embodiment Construction
[0034] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0035] The design and principle of a circularly polarized antenna based on gravity field to control liquid metal, such as figure 1 As shown, a rectangular slit is terminated on the metal reflective surface of a rectangular printed board with a thickness of 1.6mm, a relative permittivity of 4.7, and a tangent loss angle of 0.022, as shown in Figure 4 As shown, feed it with 50Ω CPW, and load the metal main radiation patch on the surface of the dielectric substrate. The circularly polarized antenna can be flipped so that the liquid metal Hg in the glass cavity is on the left and right sides of the glass container. Two parts flow, resulting in two working states: such as Figure 8 As shown, rotate 90° counterclockwise along the x-axis (state 1), due to gravity, liquid metal Hg flows into the 4 parts of the glass cavity, as Image 6As shown, the main...
