Theoretical and Empirical Study of Spatial Power Focusing Effect for Sparse Arrays at Terahertz Band

This dataset consists of channel measurement data for a sparse UPA array with a transmitting end of 7X7, antenna spacing of 15 \u03bb, operating frequency of 285-315 GHz, and a receiving end of a single antenna array. There are a total of 17 measurement points, and the antenna centers of the transmitting and receiving ends are aligned.
