Radio frequency identification (RFID) antenna integration techniques in mobile devices
First Claim
1. A mobile device, comprising:
- an antenna;
a communications module coupled to the antenna, wherein the communications module is configured to generate a first signal that is transmitted by the antenna over a wireless communications network, and to demodulate a second signal received by the antenna from the wireless communications network; and
a radio frequency identification (RFID) module coupled to the antenna, wherein the RFID module is configured to generate an interrogation signal that is transmitted by the antenna, and the RFID module is configured to demodulate a tag response signal received by the antenna.

Abstract
Methods, systems, and apparatuses for mobile devices and antenna thereof, are described herein. A mobile device include RFID reader functionality, and functionality for communicating with one or more wireless networks. A single antenna of the mobile device accommodates the network communication functionality and the RFID reader functionality. The communications network is any type of communications network, including a personal area network (PAN), a local area network (LAN), a wide area network (WAN), or a cell phone network. An antenna pattern of the antenna may be configurable. For example, a gain of the antenna may be varied, the antenna pattern may be shaped, directed, and/or polarized, the antenna pattern may be steered, and/or the antenna pattern may be ranged.
