Claim 16:
17. An antenna, including:
a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band;
a first auxiliary radiating element;
a second column of main radiating elements;
a third column of main radiating elements;
a fourth column of main radiating elements; and
a third auxiliary 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 configured to be fed with a first component of a signal, the first auxiliary radiating element 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,
wherein the first main radiating element is connected to a first output terminal of a power splitter, the first auxiliary radiating element is connected to a second output terminal of the power splitter via a phase modulation circuit, and the phase modulation circuit is configured such that the first component fed into the first main radiating element and the second component fed into the first auxiliary radiating element are substantially antiphase to each other,
wherein outputs of the power splitter at the first output terminal and the second output terminal have different phases,
wherein the first column of main radiating elements, the second column of main radiating elements, the third column of main radiating elements, and the fourth column of main radiating elements are arranged in the stated order adjacent one another in a direction transverse to an axis defined by the first column of main radiating elements and are fed separately, and the second column of main radiating elements and the fourth column of main radiating elements are vertically shifted relative to the first column of main radiating elements and the third column of main radiating elements,
wherein a main radiating element in the third column of main radiating elements corresponding to the first main radiating element is adjacent the first auxiliary radiating element, the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the main radiating element in the third column of main radiating elements corresponding to the first main radiating element, and the first auxiliary radiating element is located above the second column of main radiating elements,
wherein the third auxiliary radiating element is adjacent a third main radiating element in the second column of main radiating elements, and the third auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the third main radiating element, and
wherein a main radiating element in the fourth column of main radiating elements corresponding to the third main radiating element is adjacent the third auxiliary radiating element, the third auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the main radiating element in the fourth column of main radiating elements corresponding to the third main radiating element, and the third auxiliary radiating element is located below the third column of main radiating elements.
