The system is composed of microstrip antenna on a foam substrate, RF detector, low pass filter, amplifier, analog to digital converter, and finally digital interface with a PC. As for the antenna, we designed and implemented microstrip antenna with bandwidth of 8% using foam as dielectric substrate. We used the system to measure the power of the signal in different places at different times during the day. Using the system we assured that the signal varies depending on the traffic at different times and the location with respect to the base station.EnglishAmplifiers (electronic)BandwidthDigital instrumentsGlobal system for mobile communicationsLow pass filtersMicrostrip antennasPersonal computersRadiationSignal analysisAnalog convertesDigital converterFoam substrateRF detectorRobust controlConference Paperhttps://doi.org/10.1109/NRSC.2007.371392
