“…The TEM half-horn antenna is one half of the TEM horn antenna. It is widely used as a simple sensor for direct measurements of a pulsed E-field in traveling EM waves [22][23][24][25][26][27]. A simple TEM half-horn antenna with an impedance of 50 ohms has a low aperture efficiency (η a,eff ≈ 0.34) [26], and therefore it is unattractive for use in high-power radiators.…”

“…The half-horn sensors in the experiments [23][24][25][26] were made with the impedance of 50 ohms (W 1/ H 1 = 5) in order to match with the cable impedance. In measurements of the pulsed E-field, a parameter such as an effective length (or height) of the antenna h a,eff is often used to estimate the electrical field strength by a simple ratio E(t) = V s (t)/h a,eff , where V s (t) is the recorded voltage of the matched load.…”

Antenna Array with TEM-Horn for Radiation of High-Power Ultra Short Electromagnetic Pulses

An antenna array with short shielded transverse electromagnetic horns (S-TEM-horns) for emitting high-power radiation of ultra-short electromagnetic pulses (USEMP) has been created and researched. The antenna unit consists of an ultra-wideband antenna array with four S-TEM horns, with each connected to a two-wire HF transmission line, and these four lines are connected to an antenna feeder. This feeder is connected to a semiconductor generator with the following parameters: a 50 Ohm connector, 10–100 kV high-voltage monopolar pulses, a rise time of about 0.1 ns, FWHM = 0.2–1 ns, and pulse repetition rates of 1–100 kHz. The antenna array was designed and optimized to achieve a high efficiency of about 100% for the antenna aperture by using a 2 × 2 array with S-TEM-horns, with shielding rectangular plates for the return current. The transient responses were studied by simulation using the electromagnetic 3D code “KARAT” at the time domain and experimentally with the use of our stripline sensor for measurement of the impulse electrical field with a 0.03 ns rise time and a 7 ns duration at the traveling wave. The radiators were emitting USEMP waves with a hyperband frequency spectrum of 0.1–6 GHz. The radiation with an amplitude of 5–30 kV/m of the E-field strength at a distance of up to 20 m was successfully applied to test the electronics for immunity to electromagnetic interference.

In this study, the authors analyse the effects of the design parameters of a high‐power bipolar short‐pulsed array antenna on a beamwidth and a sidelobe of a transient radiation pattern. The analysed results can provide guidelines for synthesising a desired transient radiation performance of high‐power bipolar short pulsed‐array antennas. The analysis is performed using a formulation that consists of an element pattern and an array factor of a transient radiation pattern. To verify the validation of the studies, the analysed results of various array configurations (1 × 3, 1 × 4, 3 × 1, 4 × 1 and 2 × 2 arrays) are compared to the full‐wave simulated and measured results.
