Abstract

Methods and systems for integrating a near field communication (NFC) antenna and a Bluetooth/WLAN/ZigBee antenna are disclosed and may include configuring a first antenna that communicates at least a first RF protocol signal so that the first antenna functions as a ground plane for a second antenna when communicating at least a second RF protocol signal via the second antenna. The first antenna may include an NFC antenna and/or an RFID antenna. The second antenna may include a wireless LAN (WLAN) antenna and/or a Bluetooth antenna. The first RF protocol signal may include a NFC signal and/or a RFID signal, and the second RF protocol signal may include a Bluetooth signal and/or a Wireless LAN (WLAN) signal. The first antenna may receive a third RF protocol signal, which may include an FM signal and/or a digital video broadcast handheld (DVB-H) signal.

Claims

1. A method for supporting wireless communication, the method comprising:

configuring a first antenna that communicates at least a first RF protocol signal so that said first antenna functions as a ground plane for a second antenna when communicating at least a second RF protocol signal via said second antenna.

2. The method according to claim 1, wherein said first antenna comprises at least one of:

an NFC antenna and a RFID antenna.

3. The method according to claim 1, wherein said second antenna comprises at least one of:

a wireless LAN (WLAN) antenna and a Bluetooth antenna.

4. The method according to claim 1, wherein said at least said first RF protocol signal comprises at least one of:

a NFC signal and a RFID signal.

5. The method according to claim 1, wherein said at least said second RF protocol signal comprises at least one of:

a Bluetooth signal and a Wireless LAN (WLAN) signal.

6. The method according to claim 1, comprising receiving at least a third RF protocol signal via said first antenna.

7. The method according to claim 6, wherein said third RF protocol signal comprises at least one of the following:

an FM signal and a digital video broadcast handheld (DVB-H) signal.

8. The method according to claim 6, comprising reducing a length of said first antenna, if said third RF protocol signal comprises a DVB-H signal.

9. The method according to claim 6, comprising reducing a length of said first antenna in half utilizing a grounding circuit, if said third RF protocol signal comprises a DVB-H signal.

10. The method according to claim 9, wherein said grounding circuit comprises at least one of the following:

a switch and a grounded L-C circuit.

11. A system for supporting wireless communication, the system comprising:
