The QUIJOTE (Q U I JOint TEnerife) CMB Experiment operates from the Teide Observatory, providing a novel view of the northern sky in the frequency range from 10 to 20 GHz with the Multi Frequency Instrument (MFI). Moreover, it is targeting the detection of the B-modes in the polarization of the CMB at 30 and 40 GHz with the Thirty-Forty GHz Instrument (TFGI), with a tensor to scalar ratio goal of r=0.05. While the TFGI is in commissioning phase, the MFI, in operations since November 2012, has been observing some specific galactic regions (Génova-Santos el al. (2015), Génova-Santos el al. (2017), Poidevin et al. (2018)) but also the whole northern sky, allowing us to produce wide-survey maps of the I Q and U Stokes parameters, at 11, 13, 17 and 19 GHz. These maps are a unique view of the low frequency radio foregrounds in intensity and in polarization, providing a new data-set for the characterization of the synchrotron emission at large angular scales and of the Anomalous Microwave Emission (AME), a dust-correlated emission whose origin is still uncertain. All the maps are going to be published and available for the scientific community in the coming months. In this talk, I would like to give a brief overview of QUIJOTE, present the wide-survey maps, and mention about the preliminary scientific results achieved with the maps.
