60 GHz Planar Circular-Polarized Filtering Antenna and Its Integrated Design With Folded Reflectarray

The circular-polarized (CP) filtering antenna design based on the radiation-null-introducing technique emphasizes introducing specific filtering structures on the radiator or feeding structure. However, imperfect filtering structures are prone to generate radiation leakages toward nonboresight direc...
