1. A dipole for a multiband antenna, comprising:
four dipole arms arranged in a cross pattern, wherein the four dipole arms are arranged in a first pair of dipole arms and a second pair of dipole arms, the first pair of dipole arms are colinear and configured to radiate a first RF (Radio Frequency) signal at a first polarization angle and the second pair of dipole arms are colinear and configured to radiate a second RF signal at a second polarization angle, wherein the first polarization angle is perpendicular to the second polarization angle; and
a central region, wherein the central region is centered at an intersection of the first pair of dipole arms and the second pair of dipole arms,
wherein each of the dipole arms comprises a sequence of capacitive structures and inductive structures and a pair of high gain wings, wherein the pair of high gain wings are disposed in the central region.
