An antenna assembly for wireless communications has various components to minimize
signal influence when transmitting signals to minimize undesirable loop formation
phenomena caused by (positive) feedback of signals. Signal wave scattering and
diffraction causing back lobe radio frequency (RF) patterns are minimized by a
particular antenna assembly structure having a reflector and at least one attenuating
structural member, a metallic mesh wrapping the power cable of a feeder, a non-conductive
antenna support structure, or any combination thereof. The dimensions of the various
components, in particular the reflector and attenuators, can be varied according
to desired wireless communications environment.
