A Spread-Out Design for Dual-Band GPS Microstrip Antenna

Abstract:

This paper propose a new design of dual-band GPS microstrip antenna by spreading out the patches on the ground plane. With two independent patches, the antenna operates at two frequencies, which are available in different GPS systems. When patches are spread on the ground plane, the beam of radiation pattern shifts away and axial ratio degrades. In this design, two patches are printed on two independent substrates with a compact design, and positions of two antennas are optimized. Finally, above problems are solved with a conductive vaulted base. The design procedure is discussed, and optimized results are presented.
