Printed Antenna Arrays with Cylindrical Parabolic Reflector

Abstract

Concept of design and realization of high gain printed antenna structures is presented. They consist of antenna array, subreflector, feeding network and bal-un, all printed on the same dielectric substrate. Linear array is positioned on the axis focus of the cylindrical parabolic reflector. Results are presented for the range around 26 GHz with side lobe suppression (SLS) of 30 dB as well as for the range around 60 GHz. An example of design, optimization and realization of the high gain antenna around 23 GHz with cylindrical-parabolic reflector is given in the second part of the paper. In all reported cases agreement between simulated and measured results is very good.
