We present the status of our experiment with microwave near-fields on atom chips. Microwave near-fields are a key ingredient for atom chip applications such as quantum information processing, entanglement of Bose-Einstein condensates, atom interferometry, the study of Josephson effects and chipbased atomic clocks. We have integrated miniaturized microwave guiding structures on our atom chip. The micrometersized structures allow to generate microwave near-fields with unusually strong gradients. Through microwave dressing of hyperfine states, these can be used to create state-selective double-well potentials.
