Abstract
The present invention is Broad Area Maritime Surveillance (BAMS) radiating element which includes a plurality of dipole layers, a stripline feed layer and a cover portion. The radiating element is low-profile and may have a thickness of 180 mils. Further, the radiating element may have an operating frequency range from 5.35 GHz to 5.46 GHz and a depth of 0.083 free space wavelengths at the high end of the operating frequency range. Still further, the dipoles of the dipole layers of the BAMS radiating element vary in width from layer to layer to maximize match at the edge of the scan volume. The BAMS radiating element may be at least partially constructed of printed circuit board material, such as Rogers 4003. The BAMS radiating element may have a return loss of less than −10 decibels over its entire scan volume and frequency band.
