Abstract

A conformal antenna design method based on transform optics relates to a conformal antenna. After angularly segmenting the regions before and after the transformation respectively, the conformal stretching transformation is applied to the corresponding sub-regions before and after the transformation. According to the segmented conformal transformation method, a first group of four-directional antennas is designed, wherein the region before transformation is a circle, the region after transformation is a square, and the partition mode adopts equal-interval partition, and the simulation result includes the simulation under different background materials, different directional antenna sizes, different partition angles and different material losses; in order to further prove that the segmentedconformal transformation method has good applicability to flexible regions, a second group of six-directional irregular directional antennas is designed according to the segmented conformal transformation method, wherein the region before the transformation is a circle, the region after the transformation is an irregular hexagon, and the parameters required for the rest of the design are consistent with those in the first group, and the directional performance of the antenna under different background materials is simulated.

Description

technical field [0001] The invention relates to a conformal antenna, in particular to a transform optics-based conformal antenna design method. Background technique [0002] Based on the form invariance of Maxwell's equations under coordinate transformation, transformation optics technology is widely used in the design of various new electromagnetic devices ([1] F.Sun, B.Zheng, H.Chen, W.Jiang, S.Guo , Y.Liu, Y.Ma, and S.He, "Transformation optics: From classic theory and applications to its new branches," Laser Photonics Rev., vol.11, p.170034, Nov.2017; [2] P.Alitalo and S. Tretyakov, “Electromagnetic cloaking with metamaterials,” Mater. Today, vol.12, no.3, pp.22–29, Mar. 2009). Ordinary transformation optics methods usually require anisotropic and non-uniform materials, which is a huge problem for current materials technology. In recent years, many researchers have devoted themselves to research on transformation methods that can simplify materials, among which quasi-c...
