Abstract: A wireless device (102) having a slot antenna (104) is disclosed. The slot antenna includes at least one conducting element. Examples of the at least one conducting element include a Printed Circuit Board (PCB) ground, a metallized battery housing, a metallized frame of a display screen, a metallized housing of a keypad frame, and a metallized housing of the wireless device.

Abstract: An inductive reader device (104) communicates with a transponder (102) using electromagnetic coupling. The reader device includes a transmitter (112), a receiver (114), a first coil element (116), and a second coil element (118). The first coil element is directly connected to the transmitter to emit a radio frequency excitation signal. The first coil element receives a radio frequency response signal from the transponder via electromagnetic coupling. The second coil element is directly connected to the receiver to provide a response signal to the receiver. The second coil element is loosely or inductively coupled to the first coil element via a predetermined mutual inductance due to the spatial relationship between the first coil element and the second coil element. Hence, the second coil element receives the radio frequency response signal from the first coil element. Advantageously, a signal coupler required for the receiver is integrated with an antenna element by virtue of the second coil element.
