Abstract: A multi-band antenna array includes first antenna elements and second antenna elements. Each first antenna element has a first shape spanned by a first long axis and a first short axis, the first long axis being longer than and perpendicular to the first short axis. Each second antenna element has a second shape spanned by a second long axis and a second short axis, the second long axis being longer than and perpendicular to the second short axis. The first long axis is non-parallel to the second long axis. The first antenna element and the second antenna element resonate at a high resonance frequency band along the first long axis and the second long axis, respectively, and the first antenna element and the second antenna element further resonate at a low resonance frequency band along the first short axis and the second short axis, respectively.
