Patent ID: 7652633

Claim:
An antenna for GPS, comprising: a ground metal plate; a parasitic metal plate, disposed above the ground metal plate and connecting to the ground metal plate; a radiation metal plate, disposed above the ground metal plate, wherein the radiation metal plate is an independent metal plate, and cooperates with the parasitic metal plate to induce a resonance mode; and at least one supporting element, disposed above the ground metal plate, for supporting the radiation metal plate, wherein the ground metal plate is disposed on a first side surface of the antenna; the parasitic metal plate has a first portion and a second portion, the first portion is disposed on a second side surface of the antenna, the second portion is disposed on a third side surface of the antenna, in which the second side surface is adjacent to the first side surface, and the third side surface is opposite to the first side surface; the radiation metal plate has a first portion, a second portion and a third portion, the first portion is disposed on the second side surface, the second portion is disposed on the third side surface, the third portion is disposed on the second side surface; wherein, the second portion of the parasitic metal plate is located at a corresponding position above a first end of the ground metal plate, and extends towards the radiation metal plate; the third portion of the radiation metal plate is located at a corresponding position above a second end of the ground metal plate, and extends towards the parasitic metal plate; the second end is opposite to the first end.
