Wideband multibeam antenna for integration in small platforms

A wideband multibeam antenna for integration in small platforms such as UAV´s has been demonstrated. The demonstration was performed on a single facet comprising an 8×4 bowtie antenna elements array and a beamforming network which includes both transmitter and receiver chains and can therefore be used in multifunction systems for EW and communication. The operating frequency band chosen for this demonstrator is 6–15 GHz. Due to the modularity of the concept, the demonstrated facet can either be used stand alone or forming a faceted array depending on the required field of coverage and/or platform structure. A compact and lightweight phased array concept for 360° coverage is also discussed.
