A new multilayer ceramic balun with fractal curve for 802.11b/a is presented in this thesis. The fractal curve is implemented in balun design. By using the fractal geometry, the reduction in size of the proposed balun is evident and only several metal layers are used. Excellent results of amplitude balance and phase difference are obtained. In the mean time, there is a 1.3-GHz bandwidth of return loss and the design results in a good matching. The measured results of the LTCC multilayer ceramic balun with fractal curve agree well with the simulation. Satisfactory performance is also obtained. The dimension of the proposed Koch¡¦s and Minkowski_1st balun can be reduced by about 46.4% and 50%, respectively. Finally, the fractal balun is combined with fractal band pass filter and fractal antenna to become a passive module. Simulation of the module has been carried out and we find satisfactory results.
