This paper describes performance enhancement of high-resolved delay time estimation by pattern diversity of wheel-shaped dipole antennas for the MUSIC algorithm. We propose that the wheel-shaped dipole antennas are used to average covariance matrices weightedly with their pattern diversity without decreasing the matrix dimension and to obtain freedom of selecting sweeping frequencies. It is numerically confirmed that the wheel-shaped dipole antennas can be used to enhance capability of the delay time estimation.
