چکیده
|
The guided waveguide structures based on surface plasmons can be used to miniaturize microwave devices. by simply introducing a series of periodic truncation slits in the sspp (spoof surface plasmon polariton) waveguide, three frequency regions, namely radiating spatial wave region, guiding sspp mode region, and the cut-off region, are formed. in the frequency region of radiation, the sspp mode can be transitioned to spatial wave. consequently, double-port leaky wave antenna based on sspp waveguide is realized with beam sweep function. furthermore, a single-port antenna is demonstrated by symmetrical halving of the dual-port antenna. the half-sized single-port antenna exhibits beam steering capability and improved directivity. the proposed sspp leakage antenna can be applied to the fifth-generation (5g) mobile communication systems.
