Investigation of Use of Superimposed Surface Wave Modes

4.9/5 (12242 ratings)

Description:A method of achieving a matched radiating element in both a phased linear array and a phased two-dimensional array over wide ranges of scan angle has been investigated. This method uses two or more propagating modes in each array element such that the reflections of these modes from the array aperture produce a cancellation effect at the elemental driving terminal. An experimental 32 element linear array was constructed to verify this technique. Each radiating element consists of an open-ended waveguide driven by an end-on coaxial transition in conjunction with offset posts for the appropriate excitation of the two lowest order modes. The measured input VSWR for this experimental array after optimal adjustment of the transducer was 1.17 or less over a scan range of plus or minus 54 degrees. This result agreed very well with the predicted value. (Author).We have made it easy for you to find a PDF Ebooks without any digging.
