ANTENNA SYSTEM HAVING AN AUTOMATICALLY ADJUSTABLE DIRECTIONAL ANTENNA STRUCTURE AND METHOD FOR AUTOMATICALLY ADJUSTING A DIRECTIONAL ANTENNA STRUCTURE

摘要

An antenna system having an automatically adjustable directional antenna structure and a method for automatically adjusting a direction antenna structure are disclosed. The method includes receiving a first radiation signal, delaying the first radiation signal to obtain a first delay signal, receiving a second radiation signal, delaying the second radiation signal to obtain a second delay signal, combining the first delay signal and the second radiation signal to obtain a first combined signal, combining the first radiation signal and the second delay signal to obtain a second combined signal, detecting the power of the first combined signal to output a first amplitude, detecting the power of the second combined signal to output a second amplitude, and rotating a substrate based on the first amplitude and the second amplitude, so that a normal direction of the substrate is rotated and substantially aimed at an object.
