Abstract

Measuring the radiation characteristics of an antenna is an important step in the design process. In most cases, antennas are used in complex propagation environments, substantially different from the ideal model of the free space, where the presence of obstacles leads to multiple propagation pathways, and in some cases, when the obstacles are very close to the antennas, they become part of the radiating element. However, the characterization of an antenna is usually done in measuring sites with characteristics as close as possible to those of the free space. In most cases, such measurements are performed in an Open Area Test Site location (OATS), cleared enough of obstacles, or in an anechoic chamber. In this paper we investigate the application of the distance averaging method for antenna gain measurements in the side or back direction. The approach was successfully validation through measurements on a log-periodic dipole array (LPDA) in a regular office room.
