“…This can be seen in Figure 2 which shows a cross sectional view of the NRL Coincident Phase Center antenna element. Although two baluns per element are required, as with Choung's [5] design, they are turned 90 degrees. This allows a little more freedom to increase the height of the cavities and length of the stubs.…”

BACKGROUND:The number of topside antennas on U.S. Naval ships has almost doubled from the 1980s to the 1990s. The Navy would like to reduce the number of antennas on ships for various reasons including mutual signal interference, ship's signature, manning, spares, and life cycle costs. So, the Office of Naval Research (ONR) has been funding R&D efforts to integrate the many single-function antennas into a few common sets of broadband array antennas. These antennas must provide polarization diversity over large scan angle and broad instantaneous bandwidth.

“…Here, wavelength corresponds to the highest operating frequency. In 2001 Choung [5] and Mohuchy et al [6] reported on this type of design. Choung reported a VSWR of less than 2 over bandwidth slightly less than 3 to 1.…”
