Electromagnetic wave filter

An electromagnetic wave filter that only transmits the targeted frequency.

The electromagnetic wave filter is a bandpass filter made by combining a dielectric sheet and a conductive film lattice pattern sheet. The dielectric sheet is used as a low-pass filter (LPF) and the conductive film lattice pattern as a high-pass filter (HPF), functioning as a bandpass filter (BPF) that allows only the targeted frequency to pass through. By adjusting the dielectric constant of the sheet and the spacing of the conductive film lattice pattern, it can be tuned to the desired frequency, and research and development are ongoing in this area. Currently, tuning is being conducted with a target of 2.4 GHz, but if there are requests to adjust for other frequencies, we would like to consider that as well.
