On the Array Performance of Printed, Ultra-Wideband “Eared” Antennas

The performance of an ultra-wideband (UWB) radiator is examined in a 15-element linear-array environment. The numerically predicted array impedance is validated by means of physical measurements. The broadside scanned radiation patterns of the array are measured and proven to be extremely favorable. A zoom-in on the measured elementary radiation patterns is employed for evidencing the effect of embedding the radiator in an array environment. The study is rounded off by a post-processing phase, in which the measured array radiation pattern results are employed for predicting the array's scanning performance.
