Title: Antenna device for electromagnetic measurement

Abstract: An antenna device includes a base, an adjusting pole perpendicularly extending up from the base, a slide apparatus slidably mounted to the adjusting pole, a supporting pole forming a rack and slidably installed in the slide apparatus along a direction perpendicular to a lengthwise of the adjusting pole, and an antenna mounted to one end of the supporting pole. The slide apparatus includes a casing and a motor installed in the casing. The casing defines two opposite guiding holes for the supporting pole extending through. The motor includes a driving roller meshing with the rack. The motor drives the driving roller to rotate and mesh with the rack to allow the antenna to move along the direction perpendicular to the slide direction of the slide apparatus.
