Abstract

In this paper, the Iris circuit in the rectangular waveguide are designed and implemented. The dimension of rectangular waveguide is designed at WR340 standard (86mm x 43mm x 182mm). The signal in waveguide is fed by monopole antenna that connect to SMA (Subminiature version A) connector. The Iris circuits are designed on print circuit board, FR4 substrate with = 4.4. The results of the research showed that 1) the inductive Iris circuit acts as a high pass filter with 2.44 GHz of cutoff frequency at d/a = 0.67, 2) the capacitive Iris circuit acts as a low pass filter with 2.30 GHz of cutoff frequency at d/b = 0.075 and 3) the parallel of the inductive iris circuit and the capacitive iris circuit act as a band pass filter, supporting responses in range of 2.26-2.50 GHz of operating frequency. The results are consistent with the theoretical methods as well as commercial simulation program.
