In this thesis we propose several novel configurations of bandpass filters (BPFs)
with two transmission zeros by using the fractal theory. By means of the fractal
theory, the dimension of the proposed BPFs can be effectively reduced. Furthermore,
the proposed BPFs can be easily fabricated by using multilayer structure based on
low-temperature cofired ceramic (LTCC) technology. Under the condition of the
same dielectric thickness and coupling coefficient, we compared the conventional
square open-loop BPF with the proposed fractal ones. The results show that the
reduction in the dimension of the proposed BPFs is evident. Specifically, the
dimension of the proposed Koch¡¦s, Minkowski_1st, and Minkowski_2nd filters can be
reduced by about 36.5%, 32%, and 51.5%, respectively. Finally, the simulation and
measurement results are reported in this thesis.
