Webexisting flaws in the design and thus help in enhancing the design of reflectarray antenna. 1. Introduction A microstrip reflectarray consists of an array of radiating isolated elements printed on a grounded dielectric substrate [1–3]. These antennas are typically illuminated by a feed (horn antenna). They convert a A reflectarray antenna (or just reflectarray) consists of an array of unit cells, illuminated by a feeding antenna (source of electromagnetic waves). The feeding antenna is usually a horn. The unit cells are usually backed by a ground plane, and the incident wave reflects off them towards the direction of the … Zobraziť viac It is important to analyse the reflection magnitude $${\displaystyle S_{11} }$$ and the reflection phase $${\displaystyle \angle S_{11}}$$ across the frequency bandwidth of operation.
