Abstract
This paper presents a new concept of corrugated horn array antenna for high-resolution SAR application. The array antenna works with dual polarization, which provides additional information for signal processing techniques. The reflection coefficient |S11| ≤-20dB for system bandwidth is greater than 2.5GHz at X-band. Each element of the antenna array is placed into triangular mesh what implies sidelobes suppression below -25 dB.
