Abstract

Provided is a wireless communication apparatus including at least one two-way antenna for power recovery, a wireless block processing a wireless signal which the two-way antenna for power recovery transmits and receives, a power recovery block recovering electric power from a received signal of the two-way antenna for power recovery, and a connection switching part connecting the two-way antenna for power recovery to and switching the connection between the wireless block and the power recovery block. A duty ratio at which the connection switching part connects the two-way antenna for power recovery to the wireless block and the power recovery block is set so that the wireless block attains a desired communication speed.

Description

technical field [0001] The technology disclosed in this specification relates to a wireless communication device and an electronic device that transmit and receive a wireless wave signal, and in particular, relates to a wireless communication device and an electronic device that effectively utilize spatial radio waves when transmitting and receiving a wireless wave signal. Background technique [0002] In recent years, various wireless transmission systems using a relatively high frequency bandwidth from several hundreds of MHz to several GHz for wireless transmission are widely used. For example, wireless LAN (Local Area Network) systems using the 2GHz band, 5GHz band, etc., wireless communication equipment using the 700MHz to 2GHz band for LTE (Long Term Evolution) or 3G communication systems, and wireless Electronic devices with communication functions. [0003] In addition, it is well known to arrange a plurality of antennas to obtain diversity effects such as suppressi...
