A Versatile Design Method Applied to Conformal Metasurface Array Antenna
Accurate phase distribution and excitation incident characteristics are key issues in the design of conformal metasurface array antenna (CMAA). In this paper, we employ the improved conformal phase compensation formula to calculate the accurate phase distribution at different bending degrees. Meanwhile, elements with stable incident characteristics are designed to minimize the phase-shift deviation caused by the increase in incident angle. Furthermore, the combination of 1Bit digital coding and superposition of aperture fields enables the CMAA to adapt to different bending degrees while realizing beam-forming. Based on the designed structure, a 10 GHz dual-beam in the direction of (φ = 90°, θ = ±45°) conformal reflect-array antenna (CRAA) is fabricated by printing 15 × 15 liquid metal elements on PDMS substrate. The measured peak gain is 17.9 dBi, and the antenna maintains favorable radiation characteristics in the range of bending degree between ± 25%.
