Abstract
In this Phase I Small Business Innovation Research project, we propose to investigate and adapt a number of recently developed ultra-compact and wideband planar antenna designs for a VHF Synthetic Aperture Radar (SAR) application. The antenna is intended to be mounted on an unmanned aerial vehicle (UAV) and should cover the 20-90 MHz band. A reconfigurable antenna architecture using a switching network will be investigated to cover the entire bend in a stepped frequency mode of operation. The use of a reactive impedance surface is proposed to make the radiation pattern of the antenna unidirectional and suppress the back lobes. The effect of the mounting platform on the performance of the antenna will be simulated using in-house electromagnetic simulation codes.
