A Tunable Bandpass Frequency Selective Surface

In this paper, we propose a tunable bandpass frequency selective surface (FSS) loaded with lumped elements. The bandpass range can be adjusted by changing the value of the inductors. And an equivalent circuit model is proposed to analyze the relationship between the transmission frequency and the chip inductors. This FSS structure is simple to fabricate and has a wide frequency adjustment range of 0.5GHz to 4GHz.
