WIDE-BAND INDOOR CHANNEL CHARACTERIZATION USING MICROSTRIP PATCH ANTENNAS AT 1.95GHZ WITH DIFFERENT ANTENNA HEIGHT CONFIGURATIONS

Results highlighting the improvement in power loss factor n, RMS delay spread and correlation with distance of the indoor channel employing microstrip patch antennas mounted in an optimised height configuration are presented. Extensive power delay profile measurements with four d ifferent antenna height configurations in two laboratory environments were conducted using a vector network analyser at 1.95 GHz. Analysis o f the measurement results shows improvement of n values from 2.9 to 2 and median RMS delay spread of 10.4 ns to 6.2 ns with changes of anten na configuration.
