Directive Antenna Clutter Loss in Slant Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.
