Claim 4:
5. An antenna, including:
a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band; and
a first auxiliary radiating element,
wherein the first auxiliary radiating element is adjacent a first main radiating element in the first column of main radiating elements, and the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the first main radiating element,
wherein the first auxiliary radiating element is oriented in the same direction as the first main radiating element, and
wherein the first main radiating element is connected to a first output terminal of a power splitter and is configured to be fed with a first component of a signal, the first auxiliary radiating element is connected to a second output terminal of the power splitter via a phase modulation circuit and is configured to be fed with a second component of the signal, and the first component and the second component of the signal are substantially antiphase to each other,
and wherein a phase difference between the first component and the second component is completely provided by the phase modulation circuit.
