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

A high-gain reflect-array metasurface (MS) antenna applicable for emerging nano-satellites is presented in this paper. The designed MS antenna with an area of 96.39-by-96.39 sq. mm perfectly suits the 1-U CubeSats. It is worthwhile to mention that the proposed unit cell (UC) employed a polygonal-shaped patch whose key parameters were modified to obtain ten distinct phase responses. Then, a systematic positioning of UCs enabled the improvement of the antenna gain by focusing the main beam. Therefore, the MS antenna demonstrated a consistent high gain across a broad range of Ka-bands, with a peak value of 25.4 dBi at 28 GHz.
