Surface Wave Multipath Signals in Near-Field Microwave Imaging
Figure 7
Signal amplitudes measured at the receivers with the clinical system in Figure 2 for a single transmitter over a range of antenna heights above the tank base (3, 5, 7, 9, 11, and 13 cm) for (a) 900, (b) 1300, and (c) 1700 MHz, respectively.
