Characterization of Rayleigh fading channel at 28 GHz using narrow and wide beamwidth antennas in reverberation chamber (Invited paper)

Abstract

In this paper, channel characterization of Rayleigh fading channel at 28 GHz band is investigated. FMCW (Frequency-modulated continuous wave) radar is used as a channel sounder. The measurement is carried out inside the reverberation chamber with two different received antennas; one has 72.29° and the other has 2.40° of 3 dB beamwidth on azimuth plane. Different cases has examined with different arrangements of microwave absorbers. The obtained scattered plots and envelope distributions of Rayleigh fading channel has shown and discussed.
