Abstract

The design, fabrication and testing of dual frequency bi-orthogonally polarized microstrip patch antenna structures for GPS receivers are studied. The considered configurations include orthogonally placed coplanar rectangular patches, orthogonally stacked rectangular patches and stacked square patches. The designed antennas are fabricated according to the optimized parameters, tuned in the presence of radomes and then measured for their bandwidth, input matching, radiation pattern, gain, and polarization characteristics. Comparisons of these different configurations are presented together with theoretical and experimental results.
