A novel dual‐band bandpass filter with a compact structure and a wide stopband is proposed. The total structure includes coupled‐line stubs and coupled‐line connected sections, leading to a compact circuit. This proposed filter can be implemented easily by using single‐layer microstrip technology. The measured results of a prototype filter show that it can operate at both 1.32 and 2.67 GHz and up to the 8 GHz 15 dB stopband.
