Embodiment Construction
[0042] The invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for any limitation on the invention.
[0043]As shown in Fig. 1(a), Fig. 1(b) and Fig. 1(c), the expandable mechanism of the space planar film antenna of the present invention includes an expandable mechanism 2, and the Flat film 1, the cylindrical film in the folded state is placed inside the expandable mechanism in the folded state, and the boundary of the film is stretched in the middle of the rigid frame by the dragging cable. During the unfolding process of the rigid frame, the cylindrical film is pulled by the dragging cable to rotate and expand The expanded shape is a rigid regular polygon.
[0044] As shown in Figure 2(a), Figure 2(b) and Figure 2(c), the unfolded object is the plane of the plane film 1, and there are many folding lines distributed on the film surface, and the plane film 1 is first folded along the ...
