“…Now, if we strictly follow the method discussed in Ref. [3,4], we have to maintain symmetry in the array aperture. To maintain this symmetry we either put the array with the smallest inter-element spacing (for the highest frequency) at the center or at one corner of the multi-function aperture.…”

“…The value of 5.9mm is chosen over the maximum allowed inter-element spacing of 7.1mm for K-band because we want to keep whole number multiples between the inter-element spacings of the different regions as suggested by the designs in Ref. [3,4]. If the core has an inter-element spacing of 7.1mm, then with a multiple of two, the inter-element spacing of the next outer layer will need to be 14.2mm.…”

“…As an aside, an array with fractional ratios between the inter-element spacings has not yet been demonstrated and Kindt [3,4] considered ratios of inter-element spacings to be powers of two to minimize the number of discontinuities. However, their numerical simulations actually indicated that the effect of discontinuities is insignificant strengthening the view of the authors that the Cantrell [2], the inter layer ratios are all non-integers.…”

“…However, the number of radiating elements needed to avoid grating lobes, at the highest frequency of this wideband antenna, becomes prohibitively large resulting in a complex and costly multi-function array. There is some effort to reduce the number of elements using wavelength scaled arrays [2,3,4]but the proposed methods are limited to symmetric and/or square arrays. In one case, the operating frequencies are chosen to be a factor of two apart, limiting the flexibility of the derived architectures.…”

Standard Form 298 (Rev. 8-98)Prescribed by ANSI Std. Z39.18Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. The existing Navy ships use a separate antenna for each function, resulting in proliferation of a large number of antennas on ships to meet the numerous functional requirements. Recently, wideband phased array antennas are being developed that can perform multiple functions simultaneously to reduce the number of antennas on ships. However, the number of radiating elements needed is prohibitively large, resulting in a complex and costly multifunction phased array antenna. This report discusses novel architectures that can consolidate many functions into a single wideband phased array antenna and at the same time reduce the total number of elements needed, thereby reducing the size, weight, power, and cost compared to a conventional wideband phased array architecture. Besides the number of elements, the number of simultaneous links and element bandwidth requirements are also optimized in an effort to optimize both cost and complexity.

“…At the time, the concept was difficult to verify numerically due to the multitude of element types, and in practice, would have been too complex to implement. Recently, more powerful analysis tools have made it possible to test a more practical implementation of what we call the wavelength-scaled array concept [2]. This new approach to ultra-wide bandwidth array design, depicted in Figure 1, has core regions of different-sized elements that function for overlapping frequency bands, yet preserves critical mutual coupling paths.…”
