摘要

An implantable flexible filter is proposed in this paper. The defected ground structure is used to make the filter more compact. The pass band of the implantable filter is 5-7 GHz, and the measured minimum insertion loss is 0.84 dB and the return loss is better than 21 dB. The bending behavior of the filter is analyzed, and the insertion and return loss are consistent well with the flat. The implantable flexible filter has advantages in compact size and low loss. There will be good application prospects in implantable transceiver module and biomedical detection.
