A Small Electronic Scan Angle Antenna for Millimeter Waves

Abstract : A millimeter wave feasibility line source array has been designed and constructed as part of an effort to investigate techniques for low cost phase scan at millimeter frequencies. The array is composed of 15 edge slots on a specially constructed waveguide housing assembly containing discrete ferrite toroids. The entire array employs the series ferrite scan technique for simple, low cost scan. A description of the array design and configuration is given. Antenna patterns and the resultant scan characteristics are also presented.
