An experimental methodology to characterize the RF transmission of human body has been presented. It is a great challenge to ensure that the antennas used in the measurement will not be affected by the presence of the human body tissues, which is the key factor in order to characterize the RF transmission accurately and reliably. The proposed methodology of using tissue-embedded antennas has been...
Wireless Sensor Networks (WSNs) which utilise IEEE 802.15.4 technology operate primarily in the 2.4 GHz globally compatible ISM band. However, the wireless propagation channel in this crowded band is notoriously variable and unpredictable, and it has a significant impact on the coverage range and quality of the radio links between the wireless nodes. Therefore, the use of Frequency Diversity (FD)...
