Abstract
Abstract In four microstriplines (2, 3, 4, 5) disposed close such that they are coupled with each other, the left-hand end of the third microstripline (4) serves as an input (6), the left-hand ends of the first and second microstriplines (2, 3) and the right-hand ends of the first and fourth microstriplines (2, 5) serve as outputs (7, 8, 9, 10), and the right-hand end of the second microstripline (3) and the left-hand end of the fourth microstripline (5) are grounded.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A four-phase phase converter (1; 20; 40) comprising
first, second, third, and fourth transmission lines (2, 3,
4, 5; 21, 22, 23, 24; 42, 43, 44, 45) sequentially disposed
in parallel to couple with each other, wherein the length of the coupling sections of said
first, second, third, and fourth transmission lines (2, 3,
4, 5; 21, 22, 23, 24; 42, 43, 44, 45) is set to one fourth
the wavelength of the signal to be used at its frequency;
and among the ends of said first, second, third, and fourth
transmission lines (2, 3, 4, 5; 21, 22, 23, 24; 42, 43, 44,
45), one end serves as a signal input end (6; 25; 46), four
ends serve as signal output ends (7, 8, 9, 10; 26, 27, 28,
29; 47, 48, 49, 50), two ends are connected to the ground,
and the other one end is connected to one of the four signal
output ends.
Claim 2
Dependent Claim

Claim 1, wherein the left-hand end of said third transmission line
(4; 44) serves as a signal input end (6; 46); the left-hand ends of said first and second
transmission lines (2, 3; 42, 43) and the right-hand ends of
said first and fourth transmission lines (2, 5; 42, 45)
serve as signal output ends (7, 8, 9, 10; 47, 48, 49, 50); the right-hand end of said second transmission line (3;
43) and the left-hand end of said fourth transmission line
(5; 45) are grounded; and the right-hand end of said third transmission line (4;
44) is connected to the right-hand end of said first
transmission line (2; 42).
Claim 3
Dependent Claim
103 words

Claim 1, wherein the left-hand end of said second transmission line
(22) serves as a signal input end (25); the left-hand ends of said third and fourth
transmission lines (23, 24) and the right-hand ends of said
first and second transmission lines (21, 22) serve as signal
output ends (26, 27, 28, 29); the left-hand end of said first transmission line (21)
and the right-hand end of said fourth transmission line (24)
are grounded; and the right-hand end of said third transmission line (23)
is connected to the right-hand end of said second
transmission line (22).
Claim 4
Dependent Claim
127 words
A four-phase phase converter (30) comprising first,
second, third, and fourth transmission lines (31, 32, 33,
34) sequentially disposed in parallel in the horizontal
direction to couple with each other; wherein the length of the coupling sections of said
first, second, third, and fourth transmission lines (31, 32,
33, 34) is set to one fourth the wavelength of the signal to
be used at its frequency; and among the ends of said first, second, third, and fourth
transmission lines (31, 32, 33, 34), one end serves as a
signal input end (35), four ends serve as signal output ends
(36, 37, 38, 39), one end is connected to the ground, and
the other two ends are connected to two (36, 38) of the four
signal output ends.
Claim 5
Dependent Claim
115 words
A four-phase phase converter (30) according to
Claim 4, wherein the left-hand end of said first transmission line
(31) serves as a signal input end (35); the left-hand ends of said second and fourth
transmission (32, 34) lines and the right-hand ends of said
first and second transmission lines (31, 32) serve as signal
output ends (36, 37, 38, 39); the right-hand end of said third transmission line (33)
is grounded; and the left-hand end of said third transmission line (33)
is connected to the left-hand end of said second
transmission line (32), and the right-hand end of said
