US 7,746,288 B2 · Antenna for WWAN and integrated antenna for WWAN, GPS and WLAN

Abstract

The present invention relates to an antenna for WWAN and an integrated antenna for WWAN, WLAN, and GPS. The integrated antenna comprises a ground metal plate, a coupled WWAN antenna, a WLAN antenna, an auxiliary grounding element, and at least one supporting element. The integrated antenna of the invention can be applied to a wireless electronic device with WWAN and WLAN by utilizing the coupled WWAN antenna to induce a WWAN frequency and the WLAN antenna to induce a WLAN frequency. In addition, the ground metal plate and the auxiliary grounding element are selectively connected or not connected to a ground end of the wireless electronic device, and can be separately used to provide grounding effect. Therefore, the integrated antenna can be mounted on any part of the wireless electronic device, and can have stable electrical characteristic.
