A Wide Coverage S-Band Array with Dual Polarized Connected Bowtie Antenna Elements
Paper in proceedings, 2019

A low profile dual-polarized bowtie antenna element is studied for an S-band (3 GHz) wide-scan application in a large-scale (nearly an infinitely large) uniformly excited phased array. The study shows that the array with such elements, when connected, is capable of scanning up to ±75° at E-plane and ±15° at H-plane for horizontal and vertical polarizations respectively. The bandwidth of the infinite array with such elements across these scan angles is 10% and 25% for the active reflection coefficient of −10 dB and −5 dB respectively.
