研究目的
To explore the possibility of integration of a hybrid structure based on IDWM with a periodic sequence of auxiliary partially-metallized dielectric rods into the standard transmission line and to create an effective radiating structure on its basis.
研究成果
The experimental research demonstrated the effective integration of the hybrid structure into standard transmission lines and its potential for creating effective radiating systems. The structure showed the ability to control the radiation pattern shape and effective frequency selection in different frequency ranges.
研究不足
The study is limited to the specific configuration of the hybrid metal-dielectric structure and the frequency range of 26.5 - 35 GHz. The effectiveness of radiation is influenced by the matching with external circuits and the inhomogeneities in the dielectric elements.
1：Experimental Design and Method Selection:
The study involves the experimental research of a radiating structure based on an inverted dielectric waveguide with a metal plane and a periodic sequence of auxiliary partially-metallized dielectric rods.
