The goal is to design this type of more directive antennas that work for this kind of applications while ensuring very high gain and good directivity with an acceptable reflection coefficient.enPlanar antenna; patch; Circular polarization; high frequency 28GHz; Ka band; S-parameters; Radiation pattern; CST WMSArticle
