An antenna arrangement for a GPS signal processing device having a circuit board is disclosed. In a preferred embodiment of the invention, the arrangement comprises an antenna member mounted to the circuit board. The antenna member includes a first surface, second surface and a third surface. The third surface adjoins the first and second surfaces. The first, second and third surfaces define a cavity within which is disposed dielectric material. At least one conductive connector comprising first and second ends is in communication with the antenna member first surface. An amplifier is in communication with each conductive connector second end.

A GPS receiver includes a slot antenna having first and second surfaces. The second surface includes a semi-circular portion. The first and second surfaces define a slot within which is disposed dielectric material. The slot antenna is optimized for receiving GPS signals when in proximity to a human body. The relatively compact size of the slot antenna allows for the incorporation of the antenna into a small device that can be worn on or carried in close proximity to the body of a user. This type of antenna is not as sensitive to gain variations when in the proximity of a human body because the design has a wider aperture and thus operates better near the body. Further, this type of antenna is virtually omni-directional, i.e., it is not problematically sensitive to the location of the GPS signal source. Moreover, the design is such that the antenna arrangement can be oriented within a device in a way that maximizes the number of GPS satellites tracked.
