Study of a L2 patch antennas array for GNSS/GPS network

This work focuses precisely on design and study of an antenna, printed on Epoxy-Glass substrate, operating at L2 = 1227.6 MHz frequency. This device consists of a patch antenna array to be integrated, in a GNSS/GPS network, with the aim of detecting ionosphere disturbances associated with land-based perturbations. To address such concerns, we studied a patch antennas array, consisting of four square elements. The performances of the antennas have been measured in terms of return loss, frequency of operation, bandwidth, and radiation pattern. The numerical experiments have been performed thanks to HFSS electromagnetic simulator. As a first step, a simple square printed radiation structure was designed. In a second step, a square shape (2 * 2) antennas array has been studied.
