This paper presents a new approach for the design of a miniature microstrip cross‐coupled resonator filter. This filter has been made more compact by using cross coupling between non‐adjacent resonators and inserting parallel‐coupled lines between the ends of each resonator that are designed for reduced size. The reduced‐size resonators are integrated within a compact design to provide a λ/2 by λ/8 six‐pole filter. A novel tuning technique is used to perform fine adjustments on filter response. Results are presented to evaluate filter performance. Very close agreement is obtained between numerical and measured performance of such filters. © 2003 Wiley Periodicals, Inc.
