摘要
This paper proposes a simple novel method for angle of arrival estimation using multiple rotating omnidirectional antennas on a receiver device. The used omnidirectional microstrip antenna has a symmetrical radiation pattern with sharp minimum along the x antenna axis. An algorithm based on the fact that an angle of arrival is obtained along a direction where the measured received strength signal indicator is minimal. Our experimental results for the outdoor measurements reached a mean error of less than 4 degrees, and an indoor of less than 6 degrees.
