Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

New model of a diffraction radiation antenna intended for applications in the Ka-band is presented. The antenna has high efficiency in the frequency range of 22.9-45.8 GHz, and boasts a narrow main lobe of the radiation pattern with a width of less than 3.2°. It has been demonstrated that the antenna enables effective spatial-frequency selection of E-polarized signals within the incidence angle sector of ±82°. This property makes the presented antenna well-suited for utilization in passive imaging systems.
