Abstract
Abstract. Paper presents numerical investigation of the coaxial-to-printed microstrip transition. Results were obtained by finite-difference time domain method. Rationale of the coaxial-to-microstrip transition type. Different types of coaxial-to-microstrip transitions were considered. Due to larger area of contact and a particular form of the connector a coaxial-to-microstrip transition with metal connector was chosen for next investigation. Design and radiation characteristics of a printed quasi-Yagi antenna. Matching characteristics and radiation pattern of the quasi-Yagi antenna was calculated. Optimized feeding system of the printed quasi-Yagi antenna through coaxial-to-microstrip transition. Radiation characteristics of the printed quasi-Yagi antenna fed by coaxial-to-microstrip transition were calculated. The investigation of changes in the geometry of the coaxial-to-microstrip transition on matching characteristics of the printed antenna. The impact of changes in the geometry of transition on antenna characteristics was investigated. Conclusions. To provide high performance electrical connection from coaxial cable to microstrip line the wide band coaxial-to-microstrip transition provided low level of loss and high mechanical strength has been designed. Such transition can be used in large phased antenna arrays built of various microstrip antennas.
