Preliminary study of an antenna with a reduced BFN for dual-band beamforming

To reduce phased antenna arrays complexity we propose a new concept based on regular grid, parasitic elements and multi-excitations. This architecture enables the simplification of the beam forming network (BFN) while maintaining enough beam shaping controls. In this work, we explore the potentiality of this concept for Ku-band application in Tx/Rx band.
