This paper proposes a planar grid array antenna (GAA) at 93 GHz on low cost printed circuit board (PCB). The switched beams can be realized in a very simple and elegant way by positioning the feeding points properly. With substrate integrated waveguide (SIW) feeding structure, the antenna is able to generate 3 beams with a specific coverage of ±19° and a peak realized gain of 18.7 dBi.
