FIELD TEST AND EVALUATION OF A HELIX OPEN PERIODIC FILTER

Abstract

The test results and evaluation of a feasibility model of a helix open periodic filter are presented. Analysis of the data indicates an infinitely wide stop band with a minimum attenuation of 50 db and observed rejections as high as 70 db. Pass band data indicates a loss of less than 0.4 db and a VSWR of less than 1.6:1 across most of the pass band. The filter was capable of accommodating the full output power (minimum of 2 MW) of the AN/FPS- 65 at all frequencies. The filter tested demonstrated the feasibility of using open periodic structures for high power microwave filtering and their advantages over currently used techniques.
