Abstract

A wide band planar phased array antenna consisting of 21 by 21 Highly-Coupled Dipole (HCD) elements was designed using a combination of the `AGATE´ in-house FDTD based prediction tool and commercial microwave circuit design software. This paper discusses the challenges presented during the manufacture of this array antenna, specifically the impact of practical manufacturing considerations and their influence on the design, and the effect of manufacturing variations, relative to the `ideal´ design, on the performance of the antenna as produced.
