Abstract
AbstractThis study deals with a preliminary study of automatic beam steering property in conducting polyaniline. Polyaniline in its undoped and doped state was prepared from aniline by the chemical oxidative polymerization method. Dielectric properties of the samples were studied at S‐band microwave frequencies using cavity perturbation technique. It is found that undoped polyaniline is having greater dielectric loss and conductivity compared with the doped samples. The beam steering property is studied using a perspex rod antenna and HP 8510C vector network analyzer. The shift in the radiated beam is studied for different d.c voltages. The results show that polyaniline is a good material for beam steering applications. © 2007 Wiley Periodicals, Inc.
