An imaging microwave probe (1) with at least one measuring tip (5) on a measuring arm (2), whereby at least one of the measuring lips (5) has an antenna (6) for the detection or emission of electromagnetic signals and the measuring tip is significantly smaller in the near field than the wavelength of the electromagnetic signals, a positioning device for positioning of an object (3) for measuring relative to the measuring tip (5) in at least one spatial dimension (X, Y, Z), with a signal processing device (7) in electrical connection to the antenna (6) for conversion of the sensor signal from the antenna to a measured signal with a reduced frequency suitable for analysis or for conversion of a coupling signal with reduced frequency into a signal for transmission from the antenna (6) are described. The signal processing device (7) is integrated on the measuring tip (5) adjacent to the antenna (6) and a measured/coupling signal path (8) for the measured and/or coupling signal running from the signal processing device (7) to a measuring unit (9) arranged at a separation from the measuring tip at a frequency selected such that the measured and/or coupling signal is provided in the measuring region without significant distortion. |
