Elemento radiante de banda ancha en microstrip cerrada para arrays alimentados en serie

Abstract

A previous radiating element in transmission configuration proposed by the authors is alternatively implemented using enclosed microstrip configuration. The new implementation overcomes fabrication issues and improves its compatibility with microstrip technology. Simulation and measurement of the element show a broad impedance bandwidth and a unilateral radiation pattern. To illustrate the applicability of the element, a preliminary analysis of a leaky-wave series-fed array with 7 radiating elements is carried out. Simulation results of the array show a 48% fractional bandwidth and a single, frequencysteerable beam. The beam is able to steer 45 degrees
