Abstract
An L-shape Corner (LC) Antenna uses an L shaped antenna on the corner of a circuit board of a wireless device. The low band element is positioned and designed to be resonate along the long edge of the adjacent ground plane while the high band element (H) is positioned and designed to be resonate along the short edge of the adjacent ground plane. The PCB (printed circuit board) of the wireless device that the antenna is integrated into can provide the ground plane function. 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. Both antenna elements can be an Isolated Magnetic Dipole (IMD) antenna; conversely, one of the two antenna elements can be an IMD element.
