Abstract: A planar one-sided bull-eye leaky-wave antenna (LWA) is presented with suppressed open stopband (OSB). The antenna consists of a grounded dielectric slab (GDS) loaded on top with a periodic ...

A 60 GHz operating Bull's-Eye (BE) antenna with wide corrugations and a soft-surface is numerically and experimentally analyzed. The employment of wide grooves, rather than narrow grooves, allows a ...
