Abstract

This paper presents the development of antennas operating in Brazilian Digital TV, which ranges from 470 MHz to 860 MHz, to integrate a localization system using Digital TV signals. The directivity and antenna size are important design aspects. Different models of dipole antenna arrays are discussed for comparison purposes - the Log-Periodic of cylindrical linear conductors and the compact Log-Periodic microstrip - using Koch's fractal geometry for miniaturizing the structure.
