Standard Spiral Antennas And RF/MMW Spiral Antennas
Spiral antennas are designed to radiate or receive RF energy over very broad frequency ranges while maintaining constant beamwidth. Additional design considerations we evaluate to maximize your system performance are low axial ratio, minimal squint and very small size relative to the wavelength of the lowest operating frequency. Cobham Sensor Systems spiral antennas are designed to operate in severe airborne and ground-based environments. The antennas can also be amplitude and/or phase matched for precision DF systems.
