AB  - The paper presents concept of design and realization of the new class of printed antenna structures which consist of a linear axial array of dipoles, subreflector, feed network and a bal-un, all printed on a common dielectric substrate. The array is positioned on the axis focus of the cylindrical-parabolic reflector. Use of the reflector enables reducing back side radiation and shaping beamwidth in H-plane thus obtaining higher gain while the printed subreflector gives the possibility of achieving additional gain. Besides, by using dipoles with pentagonal shape that operate on the second resonance, enhanced bandwidth of the array has been accomplished. Four variants of such arrays have been realized: two of them with 8 radiating elements for the frequency range around 26 GHz - one with uniform and the other with tapered feed distribution, featuring gains of 27.5 dBi and 25.7 dBi, respectively. The latter has the side lobe suppression of 28 dB in E-plane. Two other arrays that are intended for ranges around 23 GHz and 60 GHz have 16 radiating elements, uniform feed distribution and measured gains of 33 dBi and 34 dBi, respectively. Bandwidths of all realized model for S11 less than -10 dB is around 30 %. In all cases agreement between simulated and measured results is very good.

AB  - The paper presents cavity backed printed antenna with circular polarization (CBACP). The antenna radiating elements are two crossed double bent dipoles that are printed on the dielectric substrate and have complex conjugated impedances. In order to diminish environmental influences the antenna is placed in the metallic cylindrical cavity. By using double bent dipoles the overall antenna dimensions are significantly reduced. CBACP is simulated and realized for operation around 5.9 GHz. Simulated and measured results show good agreement. Furthermore, investigation of cavity parameters and their effect on antenna characteristics has been carried out in order to achieve (a) minimal axial ratio, (b) maximal gain and aperture efficiency and (c) broader axial ratio bandwidth (AR LT 3 dB).

AB  - 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.
