Abstract
An L-shape Corner (LC) Antenna uses an L shaped antenna on the corner of a circuit board of a wireless device. A low band element is positioned and designed to resonate along the long dimension of the adjacent ground plane while a high band element is positioned and designed to resonate along the short dimension of the adjacent ground plane. The single antenna element provides two separate radiating sections that allow for optimization of low and high band resonances that are often required to service the cellular and other wireless frequency bands. The two radiating sections of the antenna provide different polarizations for the two resonances that assist in de-coupling the two resonances from each other.
