A printed microstrip Yagi antenna array for millimeter-wave multi-sector applications

A novel, double-printed microstrip Yagi antenna array has been proposed for multi-sector mm-wave applications around 30 GHz. The design incorporates a printed feeding structure that simplifies the fabrication process, while maintaining a low cost and a low profile. This design can be extended to incorporate H-plane feeding and possibly circular polarization to further increase the maximum data rate. This design approach can be integrated with 3D modules that consist of embedded passives, filters, and MMIC to realize a wireless system-on-package (SOP) RF front end device for very broadband applications around or above 60 GHz.
