A Holographic Antenna Based on Surface Wave Launcher

In this paper, a semi-open waveguide structure of a half-band ground medium was selected to improve the design of the TM-mode surface wave launcher(SWL), and the surface wave field generated by this SWL was simulated and analyzed. Based on the improved SWL, a corresponding holographic modulation sur...

Summary:In this paper, a semi-open waveguide structure of a half-band ground medium was selected to improve the design of the TM-mode surface wave launcher(SWL), and the surface wave field generated by this SWL was simulated and analyzed. Based on the improved SWL, a corresponding holographic modulation surface was designed, enabling the design of a holographic surface wave antenna based on the SWL. Fourier analysis was then performed on both the designed SWL and the holographic surface wave antenna to verify the correctness of the theoretical design.
