Devices developed for the aeronautic or space industries must be able to operate in harsh environments. In order to protect devices such as microstrip antennae, various coatings have to be used. Herein, we present the results of obtaining YSZ/Al2O3 h

This paper presents the study and analyses on substrate integrated waveguide (SIW) Y-type power dividers. In traditional configurations, a potential stop peak exists and separates the dominant frequency band. To overcome this drawback, a Y-type power

A microstrip and a printed monopole antenna were designed for 5.8 GHz frequency band on the same 0.5 mm thick high dielectric constant substrate. For printed monopole antenna, a new arrowhead antenna is proposed. The arrowhead monopole antenna exhibi
