In this paper, a 3D conformal meta-lens designed for manipulating electromagnetic beams via height-to-phase control is proposed. The structure consists of a 40 × 20 array of tunable unit cells fabricated using 3D printing, enabling full 360° phase compensation. A novel automatic synthesizing method (ASM) with an integrated optimization process based on genetic algorithm (GA) is adopted here to create the meta-lens.

The novelty of this design lies in the antenna's capability to suppress harmonics and higher-order modes, resulting in a significant improvement in antenna performance. Additionally, both resonators are made of dielectric materials with different relative permittivities.

- The paper introduces a high-performance circular polarized Fabry-Perot Resonator Antenna (FPRA) designed using a VBA interface between CST Microwave Studio and Matlab.
- The proposed design utilizes a partially reflective surface (PRS) for improved reflection and phase gradient, which contributes to wide bandwidth and high gain capabilities, with an impedance bandwidth of 48.58%.
- Experimental results align closely with simulations, validating the antenna's effectiveness for millimeter-wave applications, achieving a peak gain of 17.12 dB and impressive radiation efficiency of 90%.
