Near-field antenna probe design for propagating spin wave spectroscopy (PSWS) measurement

摘要

In this paper, near-field antenna probe is designed for propagating spin wave spectroscopy (PSWS) measurement. We compare the meander-line and straight-line antenna probes. Effect of the dimension parameters of antenna probe on scattering parameter is investigated. Near-field distribution and radiation pattern of these two kinds of antenna probe are discussed. Also, the placement of antenna probe is optimized for low mutual coupling. It is found that the meander-line antenna probe has better symmetric field distribution than the straight-line one.
