Abstract
This communication presents a miniaturized printed circuit board (PCB)-based surface plasmon wave antenna with high gain designed using substrate integrated waveguide (SIW) technology. The periodic grooves made on substrate provide constructive superposition of electric field due to surface plasmon resonances which lead to an antenna gain enhancement. Furthermore, using PCB with a high relative permittivity shifts the surface plasmon resonance to lower frequencies and shrinks the antenna size. The antenna is fed from the bottom layer by a feed line which couples the power to patch and surface plasmon waves through a cavity. Then, the power is propagated by the patch and SIW grooves where surface plasmons resonate. The measurement results show that a high gain of 17.4 dBi is achieved along with a narrow beamwidth and a low sidelobe level of 11 dB, approximately.
