Design and Manufacture of a Low-Profile, Ultra-Thin, Cost-Effective, Easy Production Metasurface-Based Polarization Converter With Linear and Circular Polarization Properties Suitable for Different Frequency Bands

In this article, the design and production process of a multipurpose polarization converter with a single-layer feature has been carried out using a low-profile, ultra-thin, cost-effective metasurface for different frequency band applications such as C-band (5.8–8.2 GHz), X-band (8.2–12.4 GHz), Ku-band (12.4–18.0 GHz). The polarization converter (PC) has two different features: Linear polarization (LP) and circular polarization (CP). PC has LP characteristics in the frequency ranges 6.768–7.184 GHz, 10.432–11.856 GHz, 16.896–17.520 GHz. These frequencies (6.768–7.184, 10.432–11.856, 16.896–17.520) also exhibit CP–CP functionality. In addition, it has left-handed circular polarization (LHCP) in the 8.208–8.960 GHz range and right-handed circular polarization (RHCP) in the 13.344–15.888 GHz range. A Computer Simulation Technique (CST) Studio Suite was selected for the design process of the PC. The PC is made of FR4 material and a layer thickness of 1.6 mm. The CUBE 3D device was chosen to carry out the production process. The performance analysis of the proposed converter was implemented in the frequency range of 4–20 GHz.Considering the results, it was observed that the design and production process results of the PC were compatible with each other to the desired extent.
