Abstract: A dual-band circularly-polarized (CP) antenna array based on the substrate integrated waveguide (SIW) in Ka-band is present in this paper. The antenna is consisted of SIW resonant cavity ...

Abstract: In active direction of arrivals (DOA) sensing, the multiple-input multiple-output (MIMO) radar can lead to more degrees of freedom (DOFs). The DOFs can be further increased when the fourth ...
