Abstract

A GPS receiving antenna for cellular phone is configurated into a L-shaped frame, a Y-shaped frame, or a U-shaped frame so as to achieve the best capturing effect of the radio wave radiated from the satellite. It is not necessary to use materials of specially high dielectric constant for fabrication of these antennas so that the production cost can be minimized and fabrication process can be simplified (FIG. 2).

Claims

1. A GPS receiving antenna for a cellular phone comprising:

a non-patch type frame located on a housing surface of the cellular phone and having at least two sections including first and second sections forming an L-shape, the first section being located on a top surface of the housing and the second section being located on one of a front surface and a back surface of the housing, and the first section having a width less than a width of the front surface of the housing.

2. The GPS receiving antenna according to claim 1, wherein the at least two sections include a third section located on a side surface of the housing and connected to both the first and the second sections, intersecting lines of the first, second, and third sections form a Y-shape.

3. The GPS receiving antenna according to claim 1, wherein the at least two surfaces include a third section connected to the first section on an end opposite the second section, the first, second, and third sections form a U-shape, the second section is located on the front surface of the housing, and the third section is located on the rear of the housing.
