CRANE-98838
Naval Surface Warfare Center, Crane Division (NSWC Crane) has designed and patented antenna technology related to the fabrication and use of antenna systems in transmitters and receiver systems. The inventions redesign structures or portions of the antenna that are used to shape emitted electromagnetic wave patterns, as well as the methods of manufacturing and using those antenna.

This technology was prompted by the need to increase control and minimize frequency interference while used for vehicle mounted radio frequency devices. This was applied to discone antenna to control the antenna pattern and increase overall system efficiency. Due to the mobility and environment of the antenna, the technology had to be inexpensive, rugged, and fit within limited space and weight restrictions. Furthermore, a passive system that could be used to upgrade already existing technologies was desirable.

Advantages:
-Competitive cost compared to other technologies
-Retrofit existing systems
-Customizable

Potential Applications:
-Microwave Relay Towers
-Surveillance Equipment
-Frequency Scanning Equipment
-Wi-Fi and WiMAX
-Ham Radio
-Cellular Phones
-Broadcast Communications
