摘要：

This paper presents results of experiments using a variety of antennas inside several buildings. Path loss models are presented for the 1.3 GHz and 4.0 GHz bands, and indicate little difference in indoor path loss throughout the low-microwave region. Results show that line-of-sight (LOS) channels offer significantly more cross-polarization discrimination than obstructed (OBS) channels. A profound result is that directional circularly polarized (CP) antennas always reduce rms delay spread when compared to omnidirectional and directional linearly polarized (LP) antennas in LOS. The variation of rms delay spread as a mobile moves over several wavelengths is also greatly reduced when CP antennas are used.
