1. An omni directional antenna, comprising:
- a substrate, the substrate comprising a radiation portion and a power feed portion, wherein a surface of the substrate defines a plane;
a plurality of radiating elements coupled to the radiation portion of the substrate;
at least one power dissipation element coupled to the power feed portion of the substrate;
a power feed coupled to the plurality of radiating elements; and
a ground coupled to the at least one power dissipation element, such that the at least one power dissipation element reduces an impact of the power feed on a radiation pattern of the omni directional.
