There’s nothing standard about SI2 products.

SI2 Technologies designs and manufactures flexible, high-precision antennas, arrays and signal management systems using conventional as well as patented digital printing and laser transfer manufacturing technology. Our suite of custom-designed products solves the challenges faced by the defense industry to fit and retrofit expansive communications technology into tight and unusually shaped spaces and surfaces.

We make things smart ™ – Smaller, thinner, lighter, more flexible, our products enable platforms to utilize the latest technologies for communications or signal management without increasing weight, size, power consumption or signature.

Our products enable electronics to be placed onto unconventional surfaces.

Antennas & Arrays

Working with both Government agencies and prime contractors as well as universities and non-profits, we have built a team of smart, creative and energetic technical and business experts who are passionate about our mission.

The advent of Network Centric Operations across the Department of Defense is driving the need for alternative antenna solutions that can be proliferated throughout the net while simultaneously saving space, weight and power and maintaining adaptability to multiple platforms.


SI2’s miniature communications antennas and conformal phased arrays support multiple functions including, but not limited to, communications, radar and electronic warfare applications. Our products feature lower profiles, wider bandwidths and lighter weights than conventional antennas and arrays while maintaining high efficiency.

SI2 has developed several technologies to reduce the size of our antenna and array systems. When appropriate, these technologies can be used to reduce the footprint of the system while maintaining highly efficient operation.

  • Ultra-low profiles on the order of λ/20 (where λ is the wavelength at the lowest frequency of operation)
  • Ultra-wide bandwidth up to 20:1
  • An accompanying 4x weight reduction

Signal Management

SI2’s Signal Mitigation products include flexible and conformal Frequency Selective Surfaces (FSS) for singly and doubly curved surfaces, respectively, and Resistive Films and Microwave Absorbers for challenging structural geometries and spaces.

Frequency Selective Surfaces (FSS)

SI2’s Frequency Selective Surfaces (FSS) are custom designed for specific applications as well as environmental and structural considerations.

Using SI2’s proprietary digital Direct Write printing processes, FSSs can be fabricated onto flexible substrates or conformally directly onto doubly curved surfaces.
