Abstract

An antenna system for a portable communication device comprises an antenna structure for transmitting and receiving signals. The antenna structure includes multiple feeding ports and multiple antennas of different types having a common structure fully coupling the multiple antennas together. This antenna structure is made of a conductor that can be surface mounted over a nonplanar surface. When the conductor is mounted on a nonplanar surface, the antenna structure may extend in three dimensional space around the portable communications device.
