Indoor propagation measurements using low profile and directional dual exponentially tapered slot antennas

This paper reports on the experimental set-up, results, and statistical characteristics of line-of-sight indoor wireless propagation channels using, a low-profile directional antenna on both transmit and receive. This paper compares the small-scale fading models at both microwave (5 GHz) and millimeter wave (30 GHz) frequencies. The measured results are used to determine the coefficients used in Rician and Nakagami distribution models. The results show that statistical parameters depend upon the frequency of operation and the antenna separation.
