A Planar Inverted-F Antenna (PIFA) and the related application system are disclosed. The PIFA is formed on a base board having a circular hole and a slot, and the PIFA comprises a first radiating conducting line that is formed conformally around the circular hole; a second radiating conducting line that is formed conformally around portion of the slot; and a straight radiating conducting line located between the circular and the slot, wherein one end of the first radiating conducting line is connected to one end of the straight radiating conducting line, and one end of the second radiating conducting line is merged into portion of the outer side of the first radiating conducting line adjacent to the aforementioned end of the first radiating conducting line, and an opening is formed with the straight radiating conducting line and the first radiating conducting line. Moreover, the present invention uses the arrangement of antenna diversity to install two antennas on a base board at the same time, thereby obtaining better antenna performance.
