Isotropic antenna system and notebook computer

摘要

An isotropic antenna system includes a first antenna for transmitting/receiving electric waves when a cover member installed to be capable of being open or closed with respect to a main body is open, a second antenna for transmitting/receiving electric waves when the cover member is closed, and a switch for selectively switching at least one of the first and second antennas to a predetermined RF circuit module according to the opening or closing of the cover member.
