In this thesis, we report the theoretical study of an atom interferometer using thermal (i.e. non condensed) atoms trapped on a chip, with reduced mean-field effects. To keep an adequate level of coherence, a high level of symmetry between the arms of such an interferometer is required. To achieve this goal, we describe an experimental protocol based on microwave near-fields created by two coplanar waveguides carrying currents oscillating at different frequencies. This method enables the creation of two symmetrical microwave potentials that depend on the atomic internal state, and allows a state-selective symmetrical splitting of the atoms. We mainly consider two symmetrical configurations to separate the atoms either along the longitudinal...
