1. A switched-feed antenna system comprising:
a first antenna element and a second antenna element;
a first switching circuit coupled to the first antenna element, wherein the first switching circuit is a T-switch circuit including at least three switches and is configured to direct a signal from the first antenna element to a first port of the first switching circuit or to a second port of the first switching circuit based on a setting of the at least three switches of the first switching circuit;
a second switching circuit coupled to the second antenna element, wherein the second switching circuit is a T-switch circuit including at least three switches and is configured to direct a signal from the second antenna element to a first port of the second switching circuit or to a second port of the second switching circuit based on a setting of the at least three switches of the second switching circuit, wherein
the first switching circuit and the second switching circuit are in separate logical columns such that the first port of the first switching circuit and the first port of the second switching circuit are not connected and the second port of the first switching circuit and the second port of the second switching circuit are not connected;
a first combiner configured to combine the signals at the first port of the first switching circuit and the first port of the second switching circuit into a first combined signal, wherein the first port of the first switching circuit and the first port of the second switching circuit in the separate logical columns are separately coupled to the first combiner; and
a second combiner configured to combine the signals at the second port of the first switching circuit and the second port of the second switching circuit into a second combined signal, wherein the second port of the first switching circuit and the second port of the second switching circuit in the separate logical columns are separately coupled to the second combiner.
