Abstract :
The development of a 137-element active reflect-array with MESFET amplifiers operating at X-band is presented. The array uses dual feed aperture coupled patch antennas to reduce the element size and allow for a tighter packing density. Test results for the array, including gain and radiation pattern at two frequencies, are presented to allow discussion of the array performance
