Height-Dependent Path Loss and Received Power Measurements in an Urban LoS Street Canyon at 18 GHz (FR3)

The transmitter was fixed at 6.15 m above ground and the receiver was displaced along a straight route between 26 and 96 m of horizontal separation, at heights of 0.65, 1.00 and 1.50 m. Both link ends used vertically polarized conical horn antennas of 21.1 dBi with half-power beamwidths of 13.5° and 16.5°.

The receiver was advanced on a dolly at approximately 0.3 m/s with a 1 Hz acquisition rate, giving a uniform route step of 0.2985 m, which is 17.9 wavelengths at 18 GHz. The route was traversed once per height, yielding 235 positions per height and 705 records in total.
