摘要
Two novel low-pass filters (LPFs) of wide stop-band are proposed in this paper. One filter is implemented by a photonic band-gap (PBG) microstrip structure with T-junction opened stubs and its frequency characteristics are discussed. The other filter is implemented by a PBG microstrip structure with cross-junction opened stubs. The new wide-band harmonic rejection LPFs are easy to design and fabricate. The simulated and experimental results verify the validity of the LPFs.
