Microstrip antenna design applications for RF energy harvesting

In this study, microstrip patch antennas of different sizes were designed to harvest RF energy with a characteristic impedance of 50 ohms using the transmission line model. By making various changes to the designed antennas, antennas that will operate at both single-band and dual-band frequencies have been obtained. Later, step-by-step optimizations were made with simulations to obtain better antennas. After these stages, the production of two microstrip patch antennas with the best parameters, one with a single band and the other with a dual band (Dual band), was carried out with a printing circuit (PCB). The antennas manufactured were connected to the energy calculation module and single, two and three-dimensional graphical values of voltage values, return loss (S11), gain, directivity values were examined with a multimeter.
