Abstract: In examples, systems and methods for direction finding of electromagnetic signals are described. The device includes a first antenna configured to receive electromagnetic energy. The device also includes a second antenna configured to separately receive the same electromagnetic energy. The device further includes a radome located in a receiving pathway of the first antenna, where the radome is configured to cause a predetermined phase shift that varies based on an angular position of the receiving pathway. The device includes 1 or more radio receivers to receive the signals independently from the antennas. Additionally, the direction finding device includes a processor configured to determine an angle of arrival of the electromagnetic energy based on a comparison of a phase of the electromagnetic energy received by the first antenna to a phase of the electromagnetic energy received by the second antenna.

Abstract: An antenna electromagnetic radiation steering system may include an antenna for emitting electromagnetic radiation, and a radome disposed adjacent to and at least partially enclosing the antenna, the radome including a window to pass electromagnetic radiation from the antenna to outside the radome, wherein electromagnetic radiation is directed based on a position of the window relative to the antenna.
