Abstract

A feed circuit for feeding an antenna includes: a first coupler including a first pair of opposing conductive elements; a second coupler including a second pair of opposing conductive elements; a third coupler including a third pair of opposing conductive elements; a delay line; first terminals configured to connect to the antenna; second terminals connected to a ground reference; and a feed terminal connected to the first coupler and configured to receive at least one of a transmit signal to be transmitted from the antenna or a combined received signal from the antenna. The first terminals are connected to the second coupler and the third coupler and configured to output a signal at different phases to conductive elements of the antenna. The second terminals are connected to the first coupler, the second coupler and the third coupler.
