Planar ultrawideband modular antenna array

US8325093B2

2012 A planar ultrawideband modular antenna for connection to a feed network. The antenna has a ground plane, and an array of antenna elements spaced from the ground plane, each antenna element comprising a pair of arms. A first fed arm is electrically coupled to the feed network. The grounded arm is directly electrically coupled to the ground plane. There are one or more conductors such as conductive vias electrically connecting the fed arm to the ground plane, and optionally there are one or more additional conductors electrically connecting the grounded arm to the ground plane.

Modular wideband antenna array

US9000996B2

2015 A modular wideband antenna element for connection to a feed network. There is a ground plane, and first and second flared fins above the ground plane. The fins each define a connection location that is relatively close to the ground plane and tapering to a free end located farther from the ground plane. The connection location of the first fin is electrically coupled to the feed network and the connection location of the second fin is electrically coupled to the ground plane. There are one or more additional first traces electrically connecting the first fin to the ground plane and one or more additional second traces electrically connecting the second fin to the ground plane.

Electromagnetics and Transmission Lines: Essentials for Electrical Engineering

RacademicS Publishing, LLC, Milwaukee, WI

R.A. Strangeway, S.S. Holland, J.E. Richie

2020 A uniquely focused, single-semester electromagnetics text. The book starts with the basic interaction of static charges, covers static electric and magnetic fields and dynamic electromagnetic fields, and concludes with antennas and electromagnetic interference. This broad topical coverage is achieved in a single semester by focusing on the essential topics and modulating depth of coverage where appropriate in order to retain rigor and facilitate efficient learning.

Modeling of photonic bandgap effects on scan blindnesses in printed dipole arrays

2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting

Holland, S.S.

2017 An analysis of scanblindness onset angles in printed dipole arrays with perforated dielectric substrates is presented. The periodic grid of air holes in these arrays is shown to produce a photonic bandgap (PBG), which is identified as the root cause of previously observed anomalous behavior in H-plane scans. A basic transmission line unit cell model is developed that incorporates PBG effects, and this updated model is shown to accurately predict scanblindnesseses even in cases where traditional analysis fails. This new model lays the groundwork for investigations into E-plane blindness mitigation using the PBG behavior of perforated dielectric substrates.

A review of Planar Ultrawideband Modular Antenna (PUMA) Arrays

International Symposium on Electromagnetic Theory

Logan, J.T., Holland, S.S., Schaubert, D.H., Kindt, R.W., Vouvakis, M.N.

2013 Planar Ultrawideband Modular Antenna (PUMA) arrays are low-cost, wide-scan, and low-cross polarization dual-polarized UWB arrays that combine excellent electrical performance with convenient and practical feeding/fabrication processes. Each member of the PUMA array family consists of tightly coupled horizontal dipoles over a ground plane with novel feeding schemes that enable simple PCB fabrication. This feeding eliminates the need for baluns, “cable organizers,” and other external support mechanisms to produce stand-alone, high-efficiency radiators. Additionally, all PUMA arrays consist of dual-offset dual-polarized lattice arrangements for modular, tile-based assembly. This paper will review the basic operation principles of the PUMA arrays followed by the technological evolution of the PUMA array family. Fabricated PUMA arrays and full-wave simulations of structures that can be manufactured with standard fabrication technologies will be shown along with results.

A 7–21 GHz Dual-Polarized Planar Ultrawideband Modular Antenna (PUMA) Array

IEEE Transactions on Antennas and Propagation

Holland, S.S., Schaubert, D.H., Vouvakis, M.N.

2012 The design, fabrication, and measurement of a 16 × 16 dual-polarized planar ultrawideband modular antenna (PUMA) array operating over 7-21 GHz (3:1 bandwidth) are presented. The array is comprised of tightly coupled dipoles printed on a grounded dielectric substrate and are excited by an unbalanced feeding scheme that eliminates external wideband baluns and feed organizers. The array can be assembled modularly, where each low-profile, fully planar, low-cost tile is fabricated using standard multilayer microwave PCB techniques. A unique solderless, modular interconnect mates the array to a dilation fixture that facilitates measurements using standard surface-mount assembly (SMA) connectors and terminations. After presenting the most critical design trends, simulation results of the final array in infinite, infinite × finite, and finite × finite models are compared with measurements. This prototype array exhibits a measured active VSWR.

The Planar Ultrawideband Modular Antenna (PUMA) Array

IEEE Transactions on Antennas and Propagation

S.S. Holland, M.N. Vouvakis

2012 A fully planar ultrawideband phased array with wide scan and low cross-polarization performance is introduced. The array is based on Munk's implementation of the current sheet concept, but it employs a novel feeding scheme for the tightly coupled horizontal dipoles that enables simple PCB fabrication. This feeding eliminates the need for “cable organizers” and external baluns, and when combined with dual-offset dual-polarized lattice arrangements the array can be implemented in a modular, tile-based fashion. Simple physical explanations and circuit models are derived to explain the array's operation and guide the design process. The theory and insights are subsequently used to design an exemplary dual-polarized infinite array with 5:1 bandwidth and VSWR

The banyan tree antenna array

IEEE Transactions on Antennas and Propagation

Holland, S.S., Vouvakis, M.N.

2011 A new wideband, wide-scan array is introduced, called the Banyan Tree Antenna (BTA) array, that employs modular, low-profile, low-cost elements fed directly from standard unbalanced RF interfaces. The elements consist of vertically-integrated, flared metallic fins over a ground plane that are excited by a vertical two conductor unbalanced transmission line. The antenna resembles the bunny-ear or balanced antipodal Vivaldi antenna (BAVA) designs, but most importantly uses metallic shorting posts between the fins and the ground plane that suppress a mid-band catastrophic common-mode resonance that occurs in 2D arrays of balanced radiators fed with unbalanced feeds. This work introduces simple circuit models that describe key performance attributes of the BTA array, leading to unique physical insights and design guidelines. Simulations of infinite single- and dual-polarized BTA arrays have achieved approximately two octaves of bandwidth for VSWR.
