Ultra-Wideband Patch Antenna Array With an Inclined Proximity Coupled Feed for Small Unmanned Aircraft RADAR Applications
This paper the design of a lightweight and compact patch antenna array with an inclined proximity coupled feed. The antenna array is designed for operation on a small unmanned aircraft system (sUAS) with an ultra-wideband (UWB) radar for remote sensing of soil moisture and snow. To achieve UWB imped...
