In the conventional design, the evaluation parameters for phase error were provided, and the patch-type reflectarray antenna was designed so as to decrease the phase error, but was not considered the influence of cross polarization component. In this paper, the new evaluation parameter for the cro...
A stacked microstrip reflect array antenna includes a circular disk for reflecting a remote communication signal; an antenna for receiving the communication signal reflected by the
During the design process a conical horn was developed, which illuminates the array, with symmetrical radiation pattern for all planes and for a frequency range of 76 to 81 GHz. As the FRA consists of a single layer substrate this kind of antenna could be a candidate for low-cost production...
There are two methods to obtain a circularly polarized array antenna. One is to arrange and feed linearly polarized elements (such as slots) in an appropri... K Itoh,H Shinada,T Ariga - 《Electronics & Communications in Japan》 被引量: 1发表: 2010年 Design of a Single-Layer ±45° Dua...
摘要: PROBLEM TO BE SOLVED: To provide a reflect array configured such that an electric wave scattered from a reflective plate may be scattered in a desired frequency to a desired direction that differs from a direction of specular reflection and be transmitted in other frequencies....
