【 摘 要 】

References(13)Cited-By(1)A novel compact customizable EBG (Electromagnetic Bandgap) filter operating from 2.6 to 10.0 GHz is proposed. The EBG filter is manufactured by a 2-layer PCB (Printed Circuit Board) process in RO4350 substrate with surface mounted lumped capacitors. A specific working frequency of the filter is selected on demand by adjusting the value of the capacitors, while the filter’s performance is not compromised. The experimental results show a filter with size of 2.50 × 3.00 × 1.00 mm3 in PCB achieving performance of insertion loss of 3.34 dB, 1.19 dB and 1.20 dB at 2.60 GHz, 7.71 GHz and 10.0 GHz with the capacitor of 5.1 pF, 0.5 pF and 0.3 pF respectively.
