[Legacy Report] Design of Unit Cell Antennas and Antenna Arrays for Broadcast & Aviation Applications.

---

In this presentation we will review the design of a 144 element dual polarization Vivaldi antenna array. We will demonstrate the full design process, going from a half-symmetry single polarization unit cell (most efficient for exploring/optimizing design dimensions), to a dual polarization unit cell (for determining performance specification of a dual-polarized scanned array), to a full 144 element explicit finite array. The insights
obtained by simulating the model in frequency domain Floquet unit cell analysis will be shown to be an valuable design tool in predetermining the characteristics of the full array. Additionally we will examine the design and performance of a Basestation array which employs circular polarization through the use of orthogonally fed cross dipoles. Also, we will review the analysis of a SatCom reflector antenna including radome as installed on a UAV platform. In each case electromagnetic software is used to perform parametric
studies and to examine properties such as antenna return loss, array scan blindness, and antenna field patterns.
Bill McGinn is currently a Senior Application Engineer for Ansys Inc. In the past he has worked as a hardware design engineer and was involved in the development of RF/Microwave hybrid components, MMICs and subsystems. Additionally, as a designer in a high-speed digital IC group, he led a CAD effort, and contributed to the generation of active device models for FETs. Most recently he has worked for Ansoft Corporation specializing in high frequency circuit and system level design and simulation. As an Engineering Director he
was responsible for QA, Customer Support and Production. Most recently, as a Senior Applications Engineer, he is involved with application development and product definition aimed at both component and system level design. He has most recently been involved in application development and system simulation for wireless applications as well as electromagnetic and thermal simulation of microwave components. He has written
multiple articles and holds a BSEE from Stevens Institute of Technology as well as a Business degree from St.Peters College in NJ.
