Using metamaterials on the top of the antenna’s accordance to magneto-dielectric superstrate and near zero refraction index theories causes improvement of radiation efficiency and gain of antennas. In this article, two novel metamaterial unit cells are proposed for gain and bandwidth improvement of Cylindrical Dielectric Resonator Antenna (CDRA). The first metamaterial unit cell is a […]
This research presents a new three-phase switched capacitor multilevel inverter (SCMLI) with a power enhancement capability. The structural design comprises six switches, two diodes and two capacitors to achieve a voltage gain of three times. Inherent self-balancing of capacitor voltage reduced active/passive part count, and the ability to generate bipolar output voltage without an H-bridge […]
