Abstract
Planar antenna designs that utilize surface waves (SWs) for leaky wave (LW) excitation are investigated for millimeter wave frequencies of operation. Surface-wave launchers (SWLs) are employed as the antenna source generating cylindrical SWs for bound propagation on a grounded dielectric slab (GDS). By the addition of a segmented circular strip grating configuration, a partially reflecting surface (PRS) can be realized, providing suitable conditions for 2-D leaky-wave radiation. Directive pencil beam patterns at broadside, with gain values greater than 12 dBi at 19.5 GHz, can be achieved.
