Design of an Antenna Array for GNSS/GPS Network

摘要

This work focuses precisely on the design of a smart antenna printed on dielectric substrate operating at frequency L1 = 1575.42 MHz This device consists of an antenna array to be integrated, in a GNSS/GPS network, with the aim of detecting ionosphere disturbances associated with land-based. To address such concerns, we studied an antenna array, consisting of four square elements, patch type, operating at the L1 frequency. As a first step, a simple square printed radiating structure was designed to test adaptation and radiation characteristics. In a second step, a square shape (2 * 2) antenna array has been studied. This type of sensor (networks) should respond no later than fifteen minutes after the main shock of an earthquake.
