Double-axis rotating antenna structure

Abstract

The present disclosure provides a double-axis rotating antenna structure including a base, a yaw rotating frame, an antenna assembly, a pitch rotating linkage assembly and a driving mechanism. The base includes a central gear. The yaw rotating frame is movably disposed at the base and yaws relative to the base. The antenna assembly is pivotally disposed at the yaw rotating frame and includes an antenna disc. The pitch rotating linkage assembly is connected to the antenna assembly. The driving mechanism is disposed at the yaw rotating frame and includes a worm gear, a motor and a planet gear. The worm gear is connected to the pitch rotating linkage assembly. The motor is connected to and drives the worm gear. The planet gear is engaged with the central gear and is driven by the worn gear. The motor rotates the worm gear to swing the pitch linkage assembly for driving the antenna disc to pitch and rotates the planet gear along a circumferential direction of the central gear for driving the antenna disc to yaw. Therefore, the cost is decreased.
