This work describes a wide-band Near Field Scanning Microwave Microscopy (wide-band SMM) developed in our laboratory. The system is an STM-assisted, apertureless microscope featuring nanometric resolution. The system does not exploits resonators -even though parasitic resonances do exist anyway indeed- and records directly the reflection coefficient by means of a 67 GHz VNA. The resolution is improved by a method of tip etching, while the consequent reduced sensitivity is compensated by a post-processing algorithm
