When was the last time you called someone in another state? How about another country, on another continent? How many miles away is that? Communicating over these long distances results in long (meters long!) antennas and cumbersome systems that not only take up space but require substantial labor and resources to build. While this works just fine on land, it does not translate well to all platforms of communication. For example, how can you implement those systems in the air for aircraft? What about on the ocean for naval ships?

Our integrated package solves that problem. Our electrically small antenna is designed to receive frequencies in the AM (530-1710k Hz) and FM (76-108 MHz) ranges. But it is not just an antenna: our system combines a small antenna (a mere 20 centimeters in length) with two high-impedance low-noise buffer amplifiers that respectively process signals in AM frequency range and the FM frequency range. This integration is the key to allowing that same long-distance communication, but in a smaller, lighter, easily transportable package. This technology can be used for a wider range of applications and even lower frequency ranges.
