Abstract-Koch-like fractal curve and Sierpinski Gasket are syncretized into a novel Sierpinskized Koch-like sided bow-tie (SKLB) multifractal in superior-inferior way. A K 4 S 4 SKLB multifractal dipole fed by a linearly tapered microstrip Balun is designed, simulated, fabricated and measured. The well consistent results from measurement and experiment corroborate validity of design and the multifractal antenna's superiority and advantages over its monofractal counterparts in impedance, bandwidth, directivity, efficiency, and dimension. Six good matched bands (S 11 ≤ −10 dB) with moderate gain (2.12 dBi-9.55 dBi) and high efficiency (87%-97%) are obtained within band 1.5 GHz-14.5 GHz, of which f 1 = 1.92 GHz, f 2 = 3.94 GHz, and f 3 = 5.09 GHz are generally useful. The multibands are all almost omnidirectional or quasi-omnidirectional in H-plane (P hi = 0 • , XOZ) and doughnut-shaped or dented doughnut-shaped in E-plane (P hi = 90 • , Y OZ). So it is an attractive candidate for applications like PCS, IMT2000, UMTS, WLAN, WiFi, WiMAX and other fixed or mobile wireless multiband communication systems.

“…Even if the antenna is a printed monopole, it can be studied as an asymmetric dipole and its input reactance has been studied through a transmission line model. It is well known that the resonance condition is obtained when the input impedance is purely resistive [37][38][39]. The antenna has been modelled as a transmission line periodically loaded from inductive reactances Xm represented by the half meanders shown in Fig 46. We have named half-meander the shorted transmission line of length w/2.…”

“…This deviation is observed for standard as well as perturbed Sierpinski gaskets. Estimated formulas were given for standard and perturbed Sierpinski gaskets, to locate the operational frequencies [11,[14][15][16]. The formula developed in [14] is applicable for perturbed structures, but this also provides a compromised value for the first band.…”
