1. An asymmetrical antenna, comprising:
- a substrate having opposite first and second surfaces, and first, second, third, and fourth sides;
a first radiating segment disposed on the first surface of the substrate, including;
a first conductive strip of substantially L shape disposed along the first and second sides of the substrate; and
a second conductive strip of substantially L shape having one end connected to the first conductive strip near the second side of the substrate and one free end extending toward the first side of the substrate; and
a second radiating segment disposed on the first surface of the substrate, including;
a third conductive strip of substantially L shape disposed along the first and fourth sides of the substrate; and
a fourth conductive strip of substantially L shape having one end connected to the third conductive strip near the fourth side of the substrate and one free end extending towards the first side of the substrate.

Abstract
A mobile communication device comprises a housing enclosing a circuit board that has components disposed thereon. The housing has opposite first and second surfaces. An antenna element is formed on the first surface of the housing for receiving and/or transmitting electromagnetic signals. An inner conductive layer is disposed on the second surface of the housing. The inner conductive layer is electrically connected to the antenna element and in signal communication with the circuit board.
