Abstract
An integrated antenna for WWAN, GPS, and WLAN includes a ground metal plane, a WWAN antenna, and a WLAN antenna. The WWAN antenna is connected to the ground metal plane and includes first and second radiating metal strips which induce a first resonance mode and a second resonance mode respectively. The WLAN antenna is connected to the ground metal plane and includes third and fourth radiating metal strips which induce a third resonance mode and a fourth resonance mode respectively. The integrated antenna can be used in WWAN and WLAN at the same time. The ground metal plane of the integrated antenna does not need to connect to a ground end of a wireless electronic device, and is used for grounding. Therefore, the integrated antenna can be mounted on any part of a wireless electronic device, and can have stable electrical characteristics.
