Impulse Radiating Antennas
Impulse Radiating Antennas
There are two antenna series:
● Standard Version： with 50 ohm high voltage connector and impedance adapter for antenna
● Special version： the pulse generator is placed below the ground plane.
Connected to a 30 kV, 115 ps pulse generator, the antenna can theoretically produce more than 8.3 kV/m at a distance of 20 m. The antenna can be oriented in every direction. In a receive mode, its output voltage is proportional to the incident E-field.
Applications：
● Immunity test of electronic equipment
● Buried object recognition
● Broadband jammer
● Broadband source for vulnerability research through transfer function measurement
● Industrial applications (for example, detection of underground leakage or defective pipelines)
● Avalanche rescue operations, etc
