What We Do
About Saltenna

Underwater & Along the Surfaces

 Plasmonics provide physically secure, undetectable, RADAR, broadband video, voice, and data communications from submerged machine to machine. Demonstrations available.

Saltenna can communicate in terrestrial environments.


Communications and imaging through fortified underground bunkers and tunnels, harnessing the power of Plasmonics.

Saltenna's technology has endless capabilities.

Potential Capabilities

From transmitting through metal walls to medical imaging to oil and gas applications, over-the-horizon (OTH) RADAR, terrestrial RADAR, and more.

Saltenna can fully customize communications solutions.

Plasmonic-Based Designs

You give us the desired objectives (variables: material, power, bandwidth, distance, depth, etc.) and what you’d like to achieve, and we will engineer a solution of optimized Plasmonics.

Mission & Vision

Saltenna is committed to providing innovative communication technology to the government, military, and commercial sectors. Through patented technology that harnesses the power of plasmonics, Saltenna’s technology makes communication in the harshest environments possible. 

Saltenna Communication Technology

Our Technology is plasmonics communication

We pride ourselves on making previously impossible transmissions, communications, and imaging possible and 99.999% operationally available and reliable. We build novel, game changing antenna-like devices and systems to provide superior performance in the harshest environments.

Plasmonics: surfaces, a new way to communicate

We use Plasmonics to transmit high bandwidth data. Due to a different physical mechanism of transmission, we can communicate in environments that traditional RF, acoustics, and lasers traditionally underperform or fail.

Transmit through or along the surface of seawater

We have developed several patented antenna-like devices and systems which significantly increase capacity for high-frequency RF signal transmissions through or along the surface of seawater, while providing a considerable performance advantage over other currently used undersea communication techniques. Based on initial testing, our technology provides 10-100 times improvement in size, weight, and power applications maintaining superior performance over our competitors

Breaching or enhancing secure physical environments

Sense-through walls, communications through or within secure workspaces, and penetrating RADAR/Imaging with dielectric characterization. Add secure resiliency to your communications system. Or, just improve the Wi-Fi in your building, home, or warehouse (“FutureG”).


The Saltenna Advantage

Saltenna makes previously impossible transmissions, communications, and imaging possible. Our proprietary technology also has the ability to enhance your current platform’s performance by 10-100x with SWaP-C benefit. We build novel, game changing antenna-like devices and systems to provide superior performance in the harshest environments.


Plasmonic radios: Underwater, underground, canopies, and more

Saltenna utilizes novel patented antenna-like devices that use plasmonics, which transmit in a unique pathway through free space.




Superior Underwater Defense (Submarine tech, UUVs, etc.)

Submarines, UUVs, and other underwater defense machines equipped with Saltenna’s technology can out perform conventional communication.




5G/Wi-Fi through Conductive Enclosures and Secure Workspaces

Due to the unique way in which plasmonics transmit, 5G/Wi-fi can be transmitted through conductive enclosures and secure workspaces.
