Some Practical Systems Delivered to U.S. Government Agencies
- Short backfire antennas optimized for low cross polarization (NASA)
- Helix antennas for extremely rugged configuration (DARPA)
- Radome shielding spiral antenna (U.S. Navy)
- ELF antenna with noise » 10-10 gauss/ HZ (NSF)
Ultra-Wideband Antennas
- We have designed ultra-wideband antennas covering gain and impedance performance over 60:1. It uses broadband elements and applies a genetic algorithm for loading and matching.
3-D FIPA Antenna
- A novel 3-D FIPA antenna has been designed that offers extremely wide bandwidth without the grating lobes. The antenna occupies 3-D structure and the beam width, bandwidth and phasing can be controllable.
Broadband Dipole
- Modification of the fat dipole configuration using adaptive NEC has resulted in some unique broadband dipole design. The dipoles can cover a wide frequency range and are extremely simple to construct. The most likely applications are in HF and VHF.
