240 GHz meta‐surface band pass filter and lens integration in 6G telecommunication systems

240 GHz operated meta‐surface band pass filter consisting of split‐ring resonator (SRR) matrix was simulated and measured as single and second order modes. The filter was integrated with hemispherical and Luneburg type of antenna lenses. The SRR meta‐material filter was recommended component for 6G telecommunication applications characterizing measured values of 80 GHz bandwidth, low insertion loss (−0.75 dB) and good attenuation (−8 dB) characteristics close to the band pass region, and the filters can be cascaded to enhance its filtering characteristics.
