Method and system for selecting a wireless signal based on an antenna or bias voltage
First Claim
1. A system for wireless communication, said system comprising:
- a radio frequency (RF) receiver configured to receive a wireless signal; and
a control circuit configured to;
utilize said wireless signal for frequency modulation (FM) radio broadcast signal reception, near field communications (NFC) signal reception, or radio frequency identification (RFID) signal reception; and
couple a bias voltage to one or more inductors when a frequency of the wireless signal is utilized for NFC signal reception or RFID signal reception.

Abstract
A method for wireless communication is provided and may include configuring at least one capacitor array in an antenna system to control a frequency for receiving external signals. An antenna and at least one inductor in the antenna system may be configured for receiving external signals at a first frequency. An inductor and a voltage source, a capacitor, and/or a ground reference may be configured for receiving the external signals at a different frequency if the frequency is utilized for backscattered signal reception and/or magnetically coupled signal reception. Near field communication (NFC) signals may be received at the different frequency for backscattered signals. Radio frequency identification (RFID) signals may be received at the different frequency for magnetically coupled signals. The first frequency may be within the FM frequency band. The antenna system may be configured to transmit signals to be subsequently received as backscattered signals or magnetically coupled signals.
