Array lineal de antenas planas excitadas por ranuras en la banda W

Abstract

A linear array based on three patch antennas excited by slots in W band, has been designed and is presented in this work. The design has been initially started optimizing a unique patch antenna. Then, after validating the matching and gain of this single patch, the linear array has been formed by three identical ones, obtaining a good matching and gain, with weak back radiation. A waveguide-to-microstrip transition will be necessary in the design to measure the array, therefore the simulation and measurements of a transition back-to-back has been also presented. Finally, the complete design composed of the linear array and the waveguide-to-microstrip transition has been shown without degrading the behavior of the array.
