Coding Anisotropic Metasurface with Integrated Broadband Tunable Radiation and Low-Scattering Performance

et al. 2019

In this paper, we propose a coding electromagnetic metasurface (EMMS) with integrated broadband tunable radiation and low-scattering performance. Anisotropic elements demonstrating opposite phases under x - and y -polarized incidence are investigated and coded as “0” and “1” basic elements. These elements are then arranged in an optimized layout using a simulated annealing algorithm to perform the EMMS. By this means, diffusion scattering is realized in a broadband. Meanwhile, when “0” and “1” are fed properly, the coding EMMS displays wideband linearly or circularly polarized radiation with symmetric profiles. Simulated and experimental results verify that our method offers a simple and ingenious way to integrate broadband radiation and low scattering into one single-coding EMMS.

“…Polarization reconfiguration of MS-based antenna is usually achieved through mechanical approaches (i.e., rotating MS). The polarization of the antennas using MS can be reconfigured to linear polarization (LP), right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) by rotating the MS [5,6]. In many application scenarios, polarization reconfigurable antennas with high gain are highly desirable.…”

A novel high-gain polarization reconfigurable antenna composed of a polarization conversion metasurface (PCM) and a linearly polarized source patch antenna is presented in this article. The PCM is placed above the source patch antenna with an air gap. The proposed PCM can convert the linear polarization (LP) wave radiated by the source patch antenna to LP wave, right-hand circular polarization (RHCP) wave, and left-hand circular polarization (LHCP) wave by rotating the PCM around the center of the antenna. Meanwhile, the proposed PCM can serve as the partially reflective surface (PRS) of a Fabry-Perot (FP) resonant cavity which can achieve gain enhancement. In order to validate the performance of the proposed design, a prototype antenna is fabricated and measured. Simulated and measured results agree well. From 10.43 GHz to 11.2 GHz, the polarization reconfiguration can be achieved by rotating the PCM to different angles while maintaining the high gain performance simultaneously.

“…Metamaterials (MMs), including artificial magnetic conductor (AMC), left‐hand materials (LHM), high‐impedance surface (HIS), electromagnetic band‐gap (EBG) structures and metasurface (MS), and so on, have demonstrated a number of applications in radar cross section (RCS) reduction and antenna design . Specifically, polarization conversion characteristic of MMs have been applied to design circularly polarized (CP) antennas with linearly polarized (LP) source …”

A wideband low‐profile circularly polarized (CP) slot antenna with low radar cross section (RCS) based on polarization conversion of metasurface (MS) for C‐band satellite communication system is presented and investigated. The corner‐truncated square MS is utilized to transform linearly polarized (LP) incident wave to CP radiation. Simulated results show that the CP antenna achieves an impedance bandwidth of 33.6% (4.45–6.25 GHz) and a 3‐dB axial ratio (AR) bandwidth of 18.2% (5.05–6.05 GHz). The antenna gain ranges from 7.25 to 7.95 dBic across the operating band. In addition, simulated results demonstrate that RCS of proposed antenna is reduced over 10 dB from 4.40 to 6.00 GHz with respect to traditional slot antenna. The simulated monostatic RCS of the antenna is lower than −30 dBsm in the whole operating band. Finally, an overall size of 38.8 mm × 38.8 mm × 3.5 mm ( 0.71normalλ0×0.71normalλ0×0.06normalλ0 at 5.50 GHz) antenna is fabricated and measured. The experimental results are in good agreement with the simulated ones.
