Wide scan, integrated printed circuit board, fragmented aperture array antennas

Over the last decade, fragmented aperture antennas have been developed to support bandwidths up to 33:1 and higher. Largely, these extreme bandwidth apertures have been developed to support receive applications. In this paper, we present a new design approach to increasing the scan volume to beyond 60 deg, a simplified printed circuit board fabrication approach, and a sample whole x-band (8-12 GHz) array antenna that demonstrates the new design and fabrication approach.
