IntroductionA new phased array antenna (PAA) has been designed with frequency coverage from K-to W-band. This approach takes advantage of new 3D lithographic manufacturing techniques and Harris' Current Sheet Antenna (CSA) to cover 16-110 GHz from a single aperture. In this paper, analysis results will be presented, providing greater than 50% radiation efficiency over the entire instantaneous bandwidth and good scan performance to 60 degrees. To the author's knowledge, this is the first PAA capable of continuous operation from 16-110 GHz. This exciting new technology will be applicable to future avionics systems with direct integration to transmit and receive RF photonic back-ends. Technical DiscussionThere is a growing need for millimeter wavelength (mmW) antennas as outlined by recent military programs (DARPA Hotspots, DARPA MFRF, and ONR D&I BAA 11-006) and commercial applications [1], which range from RADAR to communications. These future systems, when applied to avionics platforms, will require rapid antenna beam pointing that is only possible with a PAA. To meet this demand, wide bandwidth PAA topologies that are manufacturable at mmW frequencies are needed.Several approaches exist to cover multiple octaves of bandwidth [2-4]. However, these approaches have yet to be applied to mmW frequencies. Instead, the published literature for mmW PAAs has focused on narrow bandwidth, resonant type elements such as patch and slot antennas [5].In order to demonstrate a multi-octave PAA at mmW frequencies, one of the lower frequency antenna topologies must be migrated higher in frequency. Unfortunately, each of the aforementioned multi-octave technologies lends itself to either fabrication on or surrounded by low permittivity substrates, while current work at mmW frequencies has focused on lithographic fabrication techniques on high permittivity substrates (semiconductors, ceramics, or polymer based) or in waveguide, which is inherently narrow band. We believe that a variant of the CSA, optimized for 3D lithographic fabrication in copper, using Nuvotronics PolyStrata process, is the best way to achieve multi-octave bandwidths at mmW frequencies. 1 mm 1.5 mmFigure 1.

“…Despite exhibiting good performance, a hard bandwidth limit was imposed by the low-end loop modes spurring from the introduction of shorting vias [97]. To overcome this, a planar matching network was printed on the opposite side of the ground plane to yield a 5:1 bandwidth [97] like that shown in Fig.…”

ACKNOWLEDGMENTSI would like to begin by extending my gratitude for having the opportunity and privilege to study under the guidance of my advisor, Prof. Marinos Vouvakis, over the course of five years for my Master's and PhD research. His energy, drive, and motivation to not only teach but also to stimulate critical thinking, to invoke a practical mindset, and to create with meaning have left me with invaluable principles. I am indebted to him for challenging me and his endless patience and support throughout this research.I'd like to also thank Prof. Do-Hoon Kwon and Prof. Gopal Narayanan for serving on my dissertation committee and providing many insightful comments and support.I would like to additionally extend my gratitude to Prof. Robert Jackson, Prof.Paul Siqueira, and Prof. Joseph Bardin for serving on my research qualifying exam committee. Also, although I never had the pleasure of having him as a professor at UMass, I'd like to thank Prof. Dan Schaubert for taking the time to inadvertently introduce Vivaldi arrays to a curious kid at a phased array conference nearly six years ago; likewise thanks to Prof. Jorge Salazar for seeing some potential in that kid to encourage him to apply for graduate study at UMass. I appreciate it greatly. Ultra-wideband (UWB) electronically scanned arrays (ESA) with high efficiency, excellent polarization agility, and wide-scan matching remain essential for servicing multifunctional RF front-ends and other communications, sensing, and jamming or countermeasure systems. To this day, the most popular antenna array element in modern UWB-ESA systems is the Vivaldi, or flared notch, due to its superior widescan wide impedance bandwidth, well-known design guidelines, and practical embodiment versatility. Despite their popularity, these arrays tend to radiate unacceptably high cross-polarization levels, thus encouraging a great research opportunity.This dissertation presents the theory and design of a new class of UWB-ESAs, termed Sliced Notch Antenna (SNA) arrays, that remedy the high cross-polarization problems in Vivaldi arrays while maintaining their desirable impedance performance.The critical enabling insight of this work lays in revealing the nature of polarization viii purity or cross-polarization ratio (CPR) degradation in Vivaldi arrays to arise from a highly imbalanced ratio of longitudinal and transverse currents within the element.This work introduces a novel design strategy that intrinsically balances these currents over a UWB operating band, achieving decade-order (10:1) bandwidths and low cross-polarization. Moreover, the design approach is simple, intuitive, and can be implemented in a manner that does not inflate cost expenditures. In fact, the proposed topology can facilitate significantly reduced costs and manufacturing times

We present a design for a Tightly Coupled Dipole Array (TCDA) with wide angle scanning and a wideband compact balun. Although TCDAs are low profile, capable of wide bandwidth, good scan performance, and low cross polarization, they require a balanced feeding structure whose realization introduces significant practical challenges. Among them is developing a balun that is both compact and wideband. In this paper, we demonstrate a design for a low cost balun that fits within the existing array volume and increases the overall bandwidth of the array. This is accomplished by exploiting the balun's reactance as part of the matching network for the aperture. The final array delivers 6.3 : 1 bandwidth, ±45 • scanning in all planes, and < −10dB cross-polarization. These capabilities are believed to be unique for a low profile array with a self-contained feed.
