There is an ongoing need to bridge the gap between low-frequency omnidirectional communications systems with high-frequency low-probability of intercept (LPI) systems. Current translation efforts involve multiple antenna systems that are cumbersome and cannot be installed on the platforms which could gain the most use of them. It would be preferable to have a system capable of operating simultaneously on both the low- and high-frequency bandwidths while maintaining a small overall footprint. Until recently the antenna portion of such a system was lacking.
To address this need, Air Force researchers have developed a unique means of using existing antenna systems coupled to novel transmit and receive equipment. The technology utilizes a conformal pixelated patch-shaped or display-type antenna, whose overall geometry has a resonant frequency at the lower frequency band such as 960 MHz and a pixel element capable of beam steering above 5 GHz. This allows dual-band use of the same antenna with the low-frequency band using the entire patch (all radiating elements) in a standard manner while the high-frequency band is taking advantage of the reconfigurable nature (selectable radiating elements) of the antenna.

- System operates simultaneously in a broadcast mode on low-frequencies and in a directed mode on high-frequencies
- Capable of automatically repeating and transmitting received communications on one band into the other (receiving data on a low-frequency link and retransmitting it on a high-frequency band)
- System includes a data decoder/encoder which determines if the data needs to be resent via the high- or low-frequency Rx/Tx and properly formats the data for the appropriate system
- Applications include autonomous and manned aircraft
