摘要

A new approach to achieve beam steering at a fixed frequency by adjusting the amount of the filled dielectric material is presented. It is realized based on a standard waveguide with longitudinally slotted on the broad wall, where a layered structure is designed. By selectively filling the proposed layered structure with the low-loss transform oil (epsilonr=2.2), the effective permittivity of the medium inside the waveguide is altered, which consequently leads to the the beam steering of the waveguide antenna. To validate this concept, a six-layer container and a non-resonant 20-slot waveguide slot array operating at 13 GHz are designed. The simulation results show that the main beam scans from -47o to -6o and the gain varies from 11.88 dBi to 14.52 dBi, when the container is gradually filled with transform oil from empty to full. The results demonstrate that the proposed structure can effectively achieve beam-steering at the fixed frequency.
