Claim Text:
1. A wireless communication apparatus, comprising: a two-way antenna; a wireless circuit configured to process wireless signals which the two-way antenna transmits and receives; a power recovery circuit configured to recover electric power from a received signal of the two-way antenna; and a connection switching circuit configured to connect the two-way antenna to one of the wireless circuit and the power recovery circuit, switch the connection of the two-way antenna between the wireless circuit and the power recovery circuit, and set a duty ratio at which the connection switching circuit connects the two-way antenna to the wireless circuit and the power recovery circuit to attain a desired communication speed, the duty ratio being re-set at a higher stage by comparing the duty ratio with a setting limit of duty ratio to determine whether the duty ratio reaches the setting limit in an event the communication speed is below a predefined threshold speed.
