Abstract
Dual-band antenna elements can be used to construct a dual-beam three-column antenna array. The dual-band antenna elements include both a high-band and a low-band radiating element, which allows the dual-band antenna elements to radiate signals in two frequency bands. The dual-band antenna elements also include a resonating box to isolate the co-located radiating elements from one another, as well as to mitigate inter-band distortion. The dual-band antenna elements may be interleaved with single-band elements to achieve a dual-beam three-column antenna array. Individual elements in the dual-beam three-column antenna array may be separated by non-uniform offsets/spacings to achieve improved performance.
