The Antenna Systems Center of Excellence (COE) focuses on the design and development of innovative, high-efficiency antenna solutions to receive and transmit RF signals over a broad range of frequencies to meet the challenging communications needs of today’s military, government and commercial customers. The Antenna Systems Center of Excellence has expertise in a wide variety of antenna technologies, including: Large, medium, and small reflector antennas Phased arrays Large space-based deployable mesh reflectors Conformable antennas Smart antennas Multi-octave broadband antennas Applications for these antennas include integrated systems for missions such as terrestrial satellite communications (SATCOM), airborne communications, space-based radar, and signal collection.

Passive Intermod Testing on a Space Deployable Mesh Reflector

The Harris 1606 Compact Range is capable to 95 GHz

The company's government segment has approximately 75 antenna and 100 RF engineers on staff to support over 100 different antenna-related programs, new business opportunities, special projects and Internal Research and Development efforts. This talented group, including 13 individuals with PhD's and over 50 with master's degrees, supports the COE with Harris' proven antenna technology spanning over half a century. The innovative and creative work of Harris' technical staff has resulted in more than 85 antenna-related patents being awarded, and an additional 60 antenna-related patents in process.

Advanced antenna system development requires state-of-the-art techniques, tools and facilities. The electromagnetic computational methods used by the Center of Excellence include: Method of Moments (MoM) Finite Element Model (FEM) Geometric Theory of Diffraction (GTD) Finite Difference Time Domain (FDTD) Body of Revolution (BOR) 2-1/2 and 3-D field simulation and hybrid techniques The design tools employed are among the most advanced in the industry, including: Full TICRA Suite (GRASP8®, POS®, POD®, COBRA®, SCOPE®) C-PLAN MATLAB® ANSOFT™ OMNISYS Agilent ADS™ Eagleware® A wide variety of internally developed tools for specialized applications Harris' modern and extensive antenna test facilities allow a full array of testing from HF through millimeter wave systems. Our antenna test capabilities and facilities include:
