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.
