Abstract:
A new family of structures launching the fundamental
mode in rectangular waveguides is proposed. Individual
or stacked cavity-backed patch antennas radiate into a rectangular
waveguide, providing a good matching with a coaxial input
over a wide frequency range. The configuration results in a very
compact, colinear transition from a standard coaxial connector
to a rectangular waveguide. The components have applications
as general-purpose coaxial-to-rectangular waveguide transitions
and are well suited for low-profile, phased-array antennas. Experimental
results confirm the computational estimations of the
proposed components’ performance
