Title:
PLANAR STRUCTURE MICROWAVE SIGNAL MULTI-DISTRIBUTOR
Document Type and Number:
WIPO Patent Application WO/2008/062754
Kind Code:
A1
Abstract:
A conventional Bagley-polygon power distributor, which is of a planar structure,
has a fixed transmission path length of a quarter-wave between its input terminal
and each of two output terminals adjacent thereto and further has a shape that
is a regular, odd-numbered polygon with the length of each side being a half of
the wavelength of a designed frequency, resulting in a large size.Additionally,
the conventional Bagley-polygon power distributor has the output terminals
at its vertexes, so that the placement of the output terminals or the like might
lead to inconvenience. The present invention specifies only the characteristic
impedances of the transmission paths so as to match those impedances, and allows
any desired path lengths to be selected. In this way, the path length between
the adjacent output terminals can be appropriately adjusted to be shortened
in accordance with what is to be designed, and it is further possible to manufacture
a power distributor in which its output terminals are placed in a line.
