Broadside radiating vivaldi antenna for the 60 GHz band

A low cost, novel antenna design based on a Vivaldi structure for the 60 GHz band is presented. The antenna concept may be manufactured on a multilayer PCB but is still compact. It provides both a wide band matching as well as a high realized gain (>7 dBi) at 50 Ohm input impedance. Though based on the Vivaldi structure the main beam directs vertically with respect to the printed circuit board. The proposed antenna design is also suitable for an InPackage technology. Here we present two concepts with microstrip feed and stripline feed.
