Path Loss Model with Low Antenna Height for Microwave Bands in Residential Areas

A new path loss model of interference between mobile terminals in a residential area is proposed. The model uses invertible formulas and considers the effects on path loss characteristics produced by paths having many corners or corners with various angles. Angular profile and height pattern measurements clarify three paths that are dominant in terms of their effect on the accurate modeling of path loss characteristics in residential areas: paths along a road, paths between houses, and overroof propagation paths. Measurements taken in a residential area to verify the model’s validity show that the model is able to predict path loss with greater accuracy than conventional models. key words: path loss model, low antenna height, mobile terminal, residential area, microwave band
