摘要：
A novel design of a configurable dual-band EBG (Electromagnetic Bandgap) bandpass filter is proposed. The EBG filter is manufactured by a conventional 2-layer PCB process in RO4350 substrate with surface mounted lumped capacitors. Specific working frequency of each band of the filter can be selected on demand by adjusting the value of corresponding capacitors, while the filter's performance and compact design is not compromised. The experimental results show a filter with size of 28.00 x 28.00 x 1.52 mm(3) in PCB achieving performance of insertion loss of 2.18 dB, 2.24 dB; return loss of 14.5 dB, 11.3 dB at 2.30 GHz, 4.1 GHz respectively. The filter has band to band isolation better than 48.0 dB and spurious free region up to 9.00 GHz.
