N2  -  In this paper, a compact wideband microwave filter in X band using substrate integrated waveguide technology is designed, simulated and implemented. At first, the structure of hexagonal and semi-hexagonal microwave resonators is studied and their resonate modes, resonance frequencies and field distribution inside these resonators are investigated. Then, a second order Chebyshev filter is designed by coupling matrix of two semi-hexagonal cavities with center frequency of 10 GHz and fractional bandwidth of 20%. The first designed filter based on theoretical modeling is simulated by a full wave simulator and the geometrical parameters of the structure are adjusted for the required response. A prototype of the designed filter is implemented by TLY031 substrate and its characteristics are successfully measured. The results show that the measured results agree well with those obtained by simulation. The center frequency of the implemented filter is 8.7 GHz and it provides 27.3% bandwidth, with maximum insertion loss of 2.1 dB.
