Classification: CPC H | IPC H

Claim 8:
9. A system comprising:
at least one signal source configured to generate multiple input signals; and
a multi-beam passively-switched patch antenna array comprising:
multiple patch antenna elements collectively configured to transmit multiple electromagnetic beams in multiple beam directions;
multiple inputs each configured to receive one of the input signals, each input signal associated with one of the electromagnetic beams;
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, wherein different phase tapers are associated with different ones of the beam directions; and
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.
