Path Loss Expressions of Ultra Wideband Ground Reflection Channel

In this paper, the path loss expressions of ultra wideband (UWB) ground reflection channel are proposed. The expressions are derived from the integral formula in the terms of the closed form formula and double linear regression model based on average power loss. The break point distance are expressed in the exacted formula. The results are compared with other models and verified with the measurement result. The results are discussed in the conclusion
