A novel mobile antenna structure is presented to relay stress and strain data on railroad tracks. The antenna structure is a unique design employing dual probe-fed radiating cavities integrated with a Zigbee IEEE 802.15.4 wireless transceiver. This structure is mounted against the rail web and has a compact design to ensure survivability. A dielectric filler is employed inside each radiating cavity...
In this paper, we present an antenna design which can be integrated near the rail and which is sufficiently rugged to withstand weather conditions and rail stresses without appreciable changes in its operational mode. The proposed concept is based on fabricating a metal package mounted to the side of the rail. This metal block serves the purpose of housing the transceiver as well as the antenna. The...
This work presents an experimental study of EMC/EMI effects on cables and printed circuit boards enclosed within a complex structure comprising several cavities. To this end, a multi-cavity structure was constructed, with several measurement ports to evaluate EMI coupling under various enclosure configurations. Specifically, the measurement setup employs multiple rectangular and cylindrical cavities,...
