| Abstract: | The various technologies presented herein relate to waveguide dividers
and waveguide combiners for application in radar systems, wireless
communications, etc. Waveguide dividers-combiners can be manufactured in
accordance with custom dimensions, as well as in accordance with
waveguide standards such that the input and output ports are of a defined
dimension and have a common impedance. Various embodiments are presented
which can incorporate one or more septum(s), one or more pairs of
septums, an iris, an input matching region, a notch located on the input
waveguide arm, waveguide arms having stepped transformer regions, etc.
The various divider configurations presented herein can be utilized in
high fractional bandwidth applications, e.g., a fractional bandwidth of
about 30%, and RF applications in the Ka frequency band (e.g., 26.5-40
GHz). |
