Integrated Compact Microstrip Filters for 60 GHz Applications

An integrated microstrip filter for 60 GHz applications with image suppression of 24 dB and insertion loss of 11 dB was designed and measured. This is the first integrated filter for 60 GHz applications. Filter dimensions are 0.24 mm². An optimized compact integrated filter for IEEE 802.15.3c standard with insertion loss of 5 dB and image rejection of 30 dB was designed. We suggest optimization technique to reduce insertion loss of integrated filters. A compact, robust microstrip filter for 60 GHz applications on a PCB board, produced in an inexpensive technological process is presented.
