In this paper, the multiband fractal ring antenna fed by capacitive coupling is presented.
The Minkowski fractal
model will be used to generate the fractal ring antenna for
reducing the antenna size. Moreover, the impedance
bandwidth of antenna will be enhanced by feeding with
capacitive coupling, resulting in the antenna operation for the
application of WLAN IEEE 802.11 a/b/g (2.4 - 2.484 GHz
and 5.15 - 5.35 GHz), WiMAX IEEE 802.16a (3.3 - 3.8
GHz), and IMT advance system or 4th generation (4G) mobile
communication system (3.4 - 4.2 GHz). Furthermore, the
characteristics of the multi band fractal ring antenna will be
verified by simulationusing the full wave method of moments
(MOM) software package from IE3D. The fabricated antenna
prototype will be experimented and performed. In addition
