Impulse Radiating Antennas

The HIRA180 is an ultra-wideband radiating antenna for high intensity pulses, similar to the IRA antenna but using a ground plane as an electromagnetic mirror. This antenna produces a very narrow beam in the bore sight direction. The antenna can be oriented in every direction. The advantage of this construction compared to a full paraboloidal reflector antenna (IRA) is a better ruggedness, a broader frequency range and an improved return loss. Connected to a 30 kV / 130 ps pulse generator, the antenna can theoretically produce 15 kV/m at a distance of 10 m.
