Abstract
This invention relates to an antenna for GPS. The antenna of the invention comprises a ground metal plate, a parasitic metal plate, a radiation metal plate and at least one supporting element. The parasitic metal plate is disposed above the ground metal plate and connects to the ground metal plate. The radiation metal plate is an independent metal plate and is disposed above the ground metal plate. The parasitic metal plate cooperates with the radiation metal plate to induce a resonance mode. The supporting element is disposed on the ground metal plate and is used to support the radiation metal plate. Whereby, the problems of large size and limited receiving angle of signal according to a conventional circular polarization antenna for GPS could be improved.
