A size-reduced Wilkinson power divider is designed using defected mcirostrip structure (DMS). DMS patterns are inserted for the desirable effects of periodic structure such as size-reduction and increased line width for high characteristic impedance. As an example of circuit application, a DMS is adopted in a microwave Wilkinson power divider. The microstrip line with DMS is designed first for the 70.7Ω line impedance. The line width of 70.7Ω with DMS is wider than that of normal microstrip line. The size of designed power divider with DMS patterns is only 82% of normal power divider composed of standard microstrip lines, while the circuit performances are well preserved even after the size-reduction.
