Abstract
An apparatus includes multiple patch antenna elements configured to transmit multiple electromagnetic beams in multiple beam directions. The apparatus also includes multiple inputs each configured to receive one of multiple input signals, where each input signal is associated with one of the electromagnetic beams. The apparatus further includes multiple phase-tapered splitters each configured to receive one of the input signals, divide the received input signal into a set of sub-signals, and provide a phase taper that adjusts phases of at least some of the sub-signals in the set of sub-signals. Different phase tapers are associated with different ones of the beam directions. In addition, the apparatus includes multiple 90° hybrid transformers each configured to receive sub-signals associated with different ones of the input signals, isolate the received sub-signals from each other, and provide the isolated sub-signals to one of the patch antenna elements.
