Company Profile

AntennaSys was established in 2000 for the purpose of providing RF consulting services, custom antenna design services, and specialized antenna manufacturing to companies and government entities requiring unique antenna solutions.  We also develop, sell, and license intellectual property.  AntennaSys is a privately held New Hampshire corporation.

AntennaSys provides training for wireless product designers, RF communications professionals and advanced end-users.  We have trained groups from the U.S. government, law-enforcement, consumer product development and scientific research communities.  Our course TACOPANTS, is well known in the U.S. Military.

The president and principal engineer of AntennaSys, Spencer Webb, has designed antennas for many diverse applications for over twenty years.  Mr. Webb is an antenna consultant for numerous companies incorporating embedded antennas in their products.  A more detailed bio is here.

AntennaSys uses CST Microwave Studio for 3D electromagnetic modeling enabling the design and optimization of our antennas.  All our number crunching is done on computers from BOXX Technology, with Tesla GPUs from nVidia installed, which means fast, reliable results.

AntennaSys has in-house test and measurement equipment covering frequencies from DC through 20 GHz.  We partner with a dedicated 500-foot antenna test and measurement facility for detailed antenna characterization.  RF circuit design, both passive and active, is simulated and optimized using Agilent GENESYS software.

AntennaSys maintains an in-house CNC machine shop for prototyping and specialized low-volume manufacturing.  Our shop features a SHARP SV-2412S CNC vertical machining center and a Haas TL-1 CNC toolroom lathe. We use SolidWorks for all our mechanical design.  All our CNC Machines are programmed with Fusion 360 or CAMWorks.

AntennaSys does NOT have an exclusive agreement for representation by any agency.
