Abstract
An antenna is presented having a flared structure wherein charge is induced from one portion of the structure to another. The flared structure may be a V-shaped or other shaped element. The antenna includes at least one parasitic element to increase the gain of the antenna and extend the radiation pattern generated by the antenna in a given direction.

An antenna device, comprising:
- a substrate having two conductive layers separated by a dielectric layer;
- a first metal portion patterned onto a first layer of the substrate, the first metal portion have a flared shape;
- a second metal portion patterned onto the first layer of the substrate, the second metal portion having a second shape corresponding to the flared shape of the first metal portion and having a first side proximate the first metal portion;
- and
- a parasitic element patterned onto the first layer of the substrate, the parasitic element having a shape corresponding to the second shape positioned proximate a second side of the second metal portion.
