A simple method for creating lightweight and inexpensive microstrip patch antennas using reduced graphene oxide or acetylene black added epoxy resin was developed. The biggest goal in the method is optimizing the appropriate chemicals and production processes for producing the materials with the designed properties. Five examples of an inset‐fed microstrip patch antenna operating at approximately 2.0–12.0 GHz were designed based on the antenna‘s basic analytical formula. Their models were created in a 3D electromagnetic simulation environment. After examining the performance results of the design, the appropriate design models were produced with both 3D printer technology and wet‐chemical methods, and the experimental results were compared with the simulation results. The produced reduced graphene oxide or acetylene black added samples′ structure was illuminated with scanning electron microscope images, FTIR and Raman spectroscopy analysis. The measured S11 characteristics of the antennas provide better performance as compared to the simulated results. The measured S11 parameters for the two and three frequency bands fell substantially below −10 dB. As a result of the dielectric constants of the materials and the fabrication of the radiation plane, horizontal shifts were detected in the measurement outcomes.

We present a dish spliced concentrator (DSC) featuring hexagonal spherical sub-mirrors of uniform size. The DSC offers advantages over traditional parabolic dish concentrators, including a compact layout, cost-effectiveness, higher concentration ratio, and improved light uniformity. Its versatility allows for both uniform and focused light concentration by adjusting parameters like the focal length of the DSC, making it suitable for concentrating photovoltaic (CPV) and concentrating solar thermal (CST) applications. We design the DSC using three-dimensional (3D) vector rotation theory, implementing ray tracing and transmission characteristic analysis based on three-dimensional vector reflection theory. We establish a simulation model to evaluate the impact of geometric parameters on the DSC’s optical performance.
