  • Abstract In this work, we discuss the accuracy of measurements for
    electromagnetic. The two kinds of antenna we use are Dipole
    antenna and Broadband antenna. In general, if the antenna
    measurements we recorded at different frequencies do not exceed
    the ideal value $pm 4$dB, we would regard this site as a
    normalized site, otherwise it is not a normalized site(just a
    measurement exceeds the range). Traditionally, all we use is
    Dipole antenna, but due to difficulty of operation and inaccuracy
    of Dipole antenna, we investigate by statistical methods if we may
    use the Broadband antenna to replace the traditional Dipole
    antenna to measure. First of all, we introduce the data and
    procedure in the experiments, and fit a statistical regression
    model to predict the measurements at different frequencies in
    different test setups. Then, according to the data we collected,
    use the change point models to modify the statistical models. Our
    goal is to find a suitable statistical model for the
    measurements. Finally, we compare the measurements of Broadband
    antenna
    with Dipole antenna in the other experimental conditions keep the same.
