PROJECT TITLE :

New channel path loss model for near-ground antenna sensor networks

ABSTRACT:

The problem of very-close to-ground path loss has been recently addressed via measurements in the literature. This study proposes a unique theoretical insight into the terribly-close to-ground path loss drawback. Here, the principles of Fresnel zone are used to develop an innovative theoretical model. It is depicted that half of the Fresnel zone is abstracted by the ground for very-nearground antennas. This work shows that Fresnel zone abstraction creates an excess path loss when the heights of transmit and receive antennas are but a `critical price??. The study theoretically derives this important worth in terms of the geometric mean of the transmitter and receiver heights. Furthermore, the study proposes a model for the path loss when antennas?? heights meet this condition. Measurements are used to verify the proposed model.
