Abstract
The Groove Gap Waveguide (GGW) shows a behavior
similar to the classical rectangular waveguide (RWG),
but it is formed by two pieces which do not require metal
contact. This feature suggests the GGW as a suitable alternative
to the RGW for mm-wave frequencies, where ensuring the
proper metal contact according to the wavelength size results
challenging. Nevertheless, there is a lack of effective analysis
tools for the complex GGW topology, and assuming a direct
equivalence between the RGW and the GGW is too rough,
so that dilatory full-wave simulations are required. This work
presents a fast analysis method based on transmission line theory,
which establishes the proper correspondence between the GGW
and the RWG. In addition, below cutoff behavior of the GGW
is studied for the first time. Several numerical tests and two
manufactured prototypes validate the proposed method, which
seems very adequate to optimize future GGW structures.
