Electromagnetic Sensors & Antenna Types
Broadband Antennas

CRS developed a variety of antennas for broadband (1:10) and multiband operation. These antennas have been used for DF applications, for body-worn applications, and for various communication and surveillance application. An example of a broadband antenna is shown here. It has a specialized backing, making it almost conformal with metallic surfaces.
