Edge Truncation Effects in a Wide-Scan Phased Array of Connected Bowtie Antenna Elements

Paper in proceeding, 2020

Edge truncation effects are critical when designing a phased array, as these can lead to the variation of the active antenna impedance and radiation pattern between individual array elements. This paper investigates edge truncation effects in an array of connected Bowtie antenna elements that has been initially designed through an infinite array approach. This design represents a novel implementation of the connected-array concept that offers a wide-scan performance with up to ± 80 degrees scan range in the E-plane (in the infinite array). The goal of this study is to estimate the minimum size of a realistic finite array of such connected Bowtie antennas.
