Abstract
Recently, Intelligent Reflecting Surface (IRS), which controls the direction of reflected waves in a desired direction, has been investigated to improve the wireless environment. This paper presents outdoor measurements using a prototype IRS that controls the direction of
$\pm 45^{\circ}$
reflection by switching the incident polarization. The received power in each reflection direction was improved by more than 20 dB by placing the IRS, and the results using the IRS agreed well with the radar equation, indicating the effect of the IRS.
