Non-radiative hybrid dielectric line transition and apparatus incorporating the same

摘要

A non-radiative hybrid dielectric line transition permits a line transformation between two different types of non-radiative dielectric lines to be performed in a limited space. In addition, a non-radiative dielectric line component, an antenna apparatus, and a wireless apparatus include the above line transition. In this structure, a dielectric strip is disposed between a lower conductive plate and an upper conductive plate to form each of a hyper NRD waveguide (HNRD) and a normal NRD waveguide (NNRD). Between the two waveguides, grooves whose depths gradually become shallow from the HNRD to the NNRD are formed for receiving a third non-radiative dielectric line for performing a line transformation.
