Investigation of novel ultrawideband adaptive low-profile antenna arrays for future radioelectronic systems for dual applications
Novel method and technology of planar scanning ultrawideband antenna arrays for L-,S-, C- bands were developed. Attractive features of the arrays are wide angle scanning sector (up to ±45° in orthogonal planes), low level of cross-polar radiation, low active reflection losses (<0,3 for the absolute majority of array elements) in ultrawide frequency band with coverage up to 7:1. In addition developed antenna arrays are characterized by high efficiency (up to 95%) in L-,S-,C-bands, low weight (less than 15 kg/m2) and low profile (<λmax/10).
