Abstract:
An antenna assembly may include an antenna array having a plurality of antenna elements generally arranged along an axis. The antenna array may include a first antenna element for receiving at least one signal from a signal source, and a second antenna element spaced a distance apart from the first antenna element for receiving the at least one signal from the signal source. The antenna assembly may also include a processor coupled with the antenna array for analyzing the at least one signal and utilizing the distance between the first antenna element and the second antenna element to determine at least one of a direction or a location of the signal source. The antenna assembly may further include a memory coupled with the processor for storing a correction factor, where the processor is configured to utilize the correction factor to determine the distance between the first antenna element and the second antenna element.
