A dual-band circularly polarised antipodal Vivaldi antenna for subsurface scanning

Results in Engineering
This work reports the formation of a dual band circularly polarized antipodal Vivaldi antenna by loading it with a non-uniform array of circular polarizer-based unit cells which exhibit planar chirality. Better signal reception and less susceptibility to
