“…In recent electronic warfare, high-power jamming systems have often been used to disrupt enemy radio frequency (RF) radar systems in vehicles, ships, and aircraft by transmitting broadband interference RF waves [1]− [4]. These highpower jamming systems require phase array antennas with broadband characteristics, since the various target RF devices typically operate in multiple frequency bands.…”

This paper proposes an all-metal Vivaldi array antenna with a wide-angle impedance matching (WAIM) layer for high-power jamming systems. To reduce fabrication complexity and time, the proposed array antenna is manufactured using a metal 3D printing method. The Vivaldi unit cell, composed of a radiating flare part and an inner cavity, is extended into an 8 × 8 array with a ±45° slant configuration. To further enhance the beam steering angle, the WAIM layer is placed on top of the proposed array antenna. The performances of the proposed array antenna, such as its active reflection coefficients (ARC), gains, and array radiation patterns, are investigated in a full anechoic chamber. At a steering angle of (0 = 45°, 0 = 25°), the measured and simulated average ARCs of the center element (Port 36) with the WAIM layer are -13.2 dB and -18.5 dB, respectively. At 4 GHz, the measured and simulated bore-sight gains of the proposed array antenna are 19 dBi and 20.6 dBi, respectively. In addition, the measured and simulated bore-sight gains for the (0 = 45°, 0 = 0°) steering angle in the zx-plane are 18 dBi and 21 dBi, respectively. In the zy-plane, bore-sight gains for the (0 = 45°, 0 = 0°) steering angle are 19.3 dBi by measurement and 19.1 dBi by simulation. These results demonstrate that the proposed array antenna is suitable for highpower jamming systems because stable bore-sight gains are observed even at wide steering angles without unwanted grating lobes.INDEX TERMS High-power jamming systems, 3D printing, all-metal Vivaldi array, unit cell array, wide angle impedance matching

“…To solve this problem, the transmitter can beamform a decoy signal of a different frequency band towards the jammer. The decoy signal misleads the jammer to focus its power away from the band occupied by the legitimate signal [54], [55].…”
