Abstract: A novel planar antenna array fed by an integrated waveguide and a method for producing same is presented. The antenna array is an aperture coupled array fed by an embedded microstrip line. The embedded microstrip line transitions to a stripline feed then back to a microstrip line such that the lower ground plane of the antenna array becomes the upper ground plane with the waveguide placed on the backside of the array. The microstrip feed then couples to the waveguide for signal transmission and reception. With the exception of the waveguide itself, the elements can be simultaneously fabricated on the same RF board, using subtractive (e.g., milling, etching) and additive (e.g., deposition, 3D printing) methods.
