Abstract: Aspects of the present disclosure may be directed to a wrap-around antenna capable of being wrapped around a support structure to provide antenna patterns for a communication system. Such an assembly may be aesthetically pleasing and, because the antenna assembly allows for radiation away from the support structure, scattering effects due to interference from the support structure may be eliminated.
