This paper presents the design of tri-band planar dipole antenna for PCS and WLAN services. A modification is made in the previously presented dipole antenna design [1]. The configuration of the proposed dipole antenna is given in Figure 1(a). The antenna design consists of a printed dipole and two parasitic elements which are behaving as resonators by coupling from the driving element. The proposed...
In this paper, sierpinski-shaped dipoles are introduced in a printed log-periodic dipole antenna design. A Log Periodic Sierpinski Antenna (LPSA) is developed and the characteristics studied. Antenna size is considerably reduced, still maintaining the overall performance characteristics. The results are compared with that of a standard printed LPDA. A set of shapes of LPSA are studied and the observations...
