Abstract :
A novel circular patch bandpass filter (BPF) with multi-order harmonic suppression is proposed. Three kind of harmonic suppression structures are employed on the I/O lines to generate a wide harmonic rejection range without affecting the filter performance at the central frequency (fO). The circular patch BPF is designed at 2.4 GHz with suppression up to -60 dB, -43 dB and -31 dB measured at 2f0, 3f0 and 4f0, respectively. Additionally, the proposed filter achieve a size reduction is up to 31.2%, compared to the conventional structure.
