Electrical beam scanning is a feature enabling an antenna array to electrically control its main beam toward a desired direction. In this paper, a three-phase state element for electronically reconfigurable transmitarrays is presented. The element is made up of C-patches and modified ring slots loaded rectangular gaps. By controlling the bias state of four p-i-n diodes, three phase states are obtained. The dimension of the element is optimized by using full-wave EM simulation and performance of the element is validated by both simulation and an experimental waveguide system. A transmitarrayconsistingof12×12elementshasbeensimulated to validate the steering capabilities. Experimental results indicate the element has good characteristics and excellent phase change capabilities.

Wave Converter

Diodes are popularly used in rectifiers, which convert an ac signal into a unidirectional signal. They produce a fixed output voltage only. However, controlled switches such as thyristors are used to vary the output voltage of a converter by adjusting the delay or firing angle α of the thyristors. Phase-controlled converters are simple, efficient and less expensive. There are both single-phase and three-phase converters depending on the input supply. We also have half-wave and full-wave converters. The half-wave converter has only one polarity of output voltage and current, while for the full converter, the polarity of the output voltage can be either positive or negative. The purpose of this paper is to investigate the operation of the Single-phase full-wave rectifier. Load current for the controlled full-wave rectifier with R-L load can be either discontinuous or continuous. The paper shows how the rectifier transits from discontinuous current operation to continuous current operation.
