Abstract
A bandpass filter (BPF) configured in 3-D structures for filtering signals of ultra wide bands is disclosed, the BPF comprising sequentially stacked first to fourth dielectric substrates, wherein the first dielectric substrate is formed at a bottom surface thereof with a first ground pattern, the second dielectric substrate is formed at an upper surface thereof with a second ground pattern, and a stripline pattern is formed between the first and second dielectric substrates. The fourth dielectric substrate is formed thereon with a filter pattern and input/output coupled line patterns.
