Abstract

This paper reports a new lightweight, amplitude-tapered, wideband, linearly-polarized, dual-axis monopulse passive antenna array for synthetic aperture radar (SAR) applications. The 16 times 16 element patch array aperture is 197.7 cm² (140.61 mm from antenna edge to antenna edge in both orthogonal directions). The array is 2.98 mm thick and provides 17% instantaneous bandwidth in Ku-band. It is easily manufactured using photolithographic etching techniques.
