Abstract

This paper presents a complete procedure for the design of printed log-periodic antennas. An investigation on the coaxial-to-parallel-strip transition usually present in this kind of antenna is discussed in detail and it is demonstrated to be very critical for the achievement of the desired impedance bandwidth. Furthermore, in order to reduce the overall antenna size, the dipoles have been implemented based on Koch fractals. It has been demonstrated that the use of Koch fractals allowed reducing the antenna area by 25 % in comparison to the classical printed log-periodic structure. Both designs have been optimized for the frequency range 2.3 – 6 GHz, so as to cover several wireless services, such as WLAN, mobile communications and WiMAX, among other applications. Experimental results validate the proposed design strategy.
