Abstract:
This work focuses on design and study of low cost corners truncated antennas arrays, printed on alumina,
operating at L1/L2 GPS frequencies. This device consists on one patch antennas array to be integrated, in a
warning system, with the aim of detecting ionosphere disturbances associated with land-based perturbations
and tsunami's arrivals at the coast. To address such concerns, we studied a dual frequency patch antennas
array. The performances of the antenna have been measured in terms of return loss, frequency of operation,
axial ratio, bandwidth, and radiation pattern. Particularity and major advantage of this antenna, compared to
conventional marketed GPS antennas, is the simultaneous use of both GPS frequencies L1 and L2.
