Abstract

One or more of the embodiments of a dual band stacked patch antenna described herein employ an integrated arrangement of a global positioning system (GPS) antenna and a satellite digital audio radio service (SDARS) antenna. The dual band antenna receives right hand circularly polarized GPS signals in a first frequency band, left hand circularly polarized SDARS signals in a second frequency band, and vertical linear polarized SDARS signals in the second band. The dual band antenna includes a ground plane element, an upper radiating element (which is primarily utilized to receive SDARS signals), dielectric material between the ground plane element and the upper radiating element, and a lower radiating element (which is primarily utilized to receive GPS signals) surrounded by the dielectric material. The dual band antenna uses only one conductive signal feed to receive both GPS and SDARS signals.

Description

technical field [0001] The subject matter described herein relates generally to patch antennas, and more particularly to an integrated dual-band stacked patch antenna suitable for use with Global Positioning System (GPS) signals and Satellite Digital Audio Radio Service (SDARS) signals. Background technique [0002] Existing techniques include radio frequency (RF) and microwave antenna design, construction and configuration. Such antennas are utilized in many different applications to wirelessly transmit and receive signals conveying information or data. For example, a modern automobile (or other vehicle) may utilize many antennas to receive signals throughout the radio frequency spectrum. Indeed, the vehicle may include one or more of the following systems: AM / FM radio; satellite radio; GPS-based navigation system; and mobile telecommunications system. Certain vehicles may include antennas to receive SDARS signals and / or GPS signals. In this case, L1 GPS signals are used...
