One-Dimensional Super-Wide-Band 8 × 4 Van Atta Antenna Array

This paper presents a super-wide-band(SWB) 8 × 4 Van Atta antenna array with a working bandwidth of 2GHz-29.474GHz and a relative working bandwidth of 175%,covering S, C, X, Ku, and K bands. The simulation results show that the −10dB retrodirective angle range of the proposed Monostatic radar cross section (RCS) is 32°-132°, and in the frequency range of 3.026-28.904GHz, the −6dB angle range of the Monostatic RCS is 66°-92°. The Monostatic RCS has a 20dB lift compared to equal sized metal floor. In addition, the array directly uses coaxial connections to connect antenna pairs without requiring a complex feed network.
