Design of Power Dividers using Defected Microstrip Structure and an Analytically Calculated Characteristic Line Impedance
AbstractIn this work, a defected microstrip structure (DMS), methods to calculate the new characteristic impedance of DMS line, and, as an application example, a design of microwave wilkinson power dividers using DMS pattern are described. DMS patterns are inserted for the desirable effects of periodic structure such as size-reduction and increased line width for high characteristic impedance. In order to calculate the proper characteristic impedance of DMS microstrip line, the quarter-wavelength transformer model method and an analytic calculation method are adopted. As an example, the DMS microstrip line with 70.7 characteristic impedance is designed, calculated and inserted into the wilkinson power divider. The size of designed power divider with DMS patterns is only 82% of a reference power divider composed of normal microstrip lines, while the circuit performances are very well preserved even after the size-reduction.
