A new study published on Nature Communications describes biochip technology for rapid genetic screening, a potentially revolutionary solution that could turn virus and disease detection into a.
These metasurfaces outperform existing LCD and LED tech in devices such as televisions and mobile phones. They are expected to make electronic devices thinner, have higher resolution, and use less energy.
This paper presents a high gain circular polarized Fabry-Pérot antenna for CubeSat applications. A key idea is the implementation of cavity using a 5× 5 Metasurface ground surface to improve the total gain of the proposed antenna design. The two opposite corners of the radiating patch elements are truncated to achieve a right-hand circular polarisation (RHCP). The presented simulation results show that the proposed antenna provides a high gain of 9.4 dBi, -10 dB bandwidth 12% (2.42-2.73 GHz) with a reflection coefficient of -15.6 dB at 2.5GHz and a -3dB axial ratio bandwidth of 1.6% at 2.5GHz.
