Abstract

The authors describe the implementation of a seven-element CP array using slot-coupled patches. The approach used results in an array structure that has low profile and light weight and is very simple to fabricate without any coaxial feedthrough. Because the feed circuit is etched on a separated layer, space is available for other circuits, such as filters, amplifiers, and phase shifters. This array can therefore be an active module. A breadboard model was designed, fabricated, and tested. Excellent measured results were obtained.<>
