Classification: CPC H | IPC H

Claim 18:
19. A method comprising:
receiving a first input signal;
dividing the first input signal into a first set of multiple sub-signals and adjusting phases of at least some of the sub-signals in the first set of sub-signals according to a first phase taper;
feeding the phase-adjusted first set of sub-signals to multiple patch antenna elements through multiple 90° hybrid transformers;
transmitting a first electromagnetic beam in a first beam direction using the patch antenna elements based on the phase-adjusted first set of sub-signals;
receiving a second input signal;
dividing the second input signal into a second set of multiple sub-signals and adjusting phases of at least some of the sub-signals in the second set of sub-signals according to a second phase taper;
feeding the phase-adjusted second set of sub-signals to the patch antenna elements through the 90° hybrid transformers, the 90° hybrid transformers isolating the first and second sets of sub-signals from each another; and
transmitting a second electromagnetic beam in a second beam direction using the patch antenna elements based on the phase-adjusted second set of sub-signals;
wherein the first and second beam directions are based on the first and second phase tapers, respectively.
