Ground reflection mesurements for develpoment of a physical mean effective gain modal applicable to portable device antennas

Abstract

This paper presents the development of a technique which attempts to characterizes the ground plane characteristics via measurement. The mean effective gain, which assesses the general property of antenna reception capability in the environment, has been used for handset antennas such as GPS reception antennas. However, current models are established on a rough assumption about the ground properties and employ statistical models to address the ground reflection. In this work, we try to assess ground properties using actual measurements. The results can be forwarded to establish a physic-based ground reflection model for antenna mean effective gain assessment.
