Opis:
This paper presents how to design and simulate a passband rectangular waveguide filters based on direct coupled resonators operating at 12 GHz. The modeled filters are characterized by a cross coupling that produces a single attenuation pole at finite frequency used to shape the bandpass response. Resonators provide bandpass filter designs with a pseudo-elliptic response using HFSS simulators. Transmission zeros are obtained through coupling between the fundamental mode and high mode. The filter structures are validated leading to obtain transmission zeros close to the passband. The simulated waveguide filters with a centre frequency exhibit an insertion loss of -0.4/0.3dB and a return loss of −20/23dB for a bandwidth ranging from 11.85GHz to 12.15GHz that shows good electromagnetic responses for the simulated filters.

Opis:
The waveguide filter structure is treated by two softwares (HFSS (High Frequency Structure Simulator) and CST (Computer Simulation Technology)). Numerical example is given in this article to demonstrate, step by step, the application of the approach to the design of resonator, direct coupled waveguide and microstrip filters based on electromagnetic (EM) simulations. For this design procedure, the filter structure is simulated by successively adding one resonator at a time. To continue the work illustrates how to design a fourth order coupled resonator based rectangular waveguide circuit in the traditional way. With a large number of variables, such tuning work consumes a lot of time and the convergence of the final result is not guaranteed. A fourth order X-band bandpass filter with a center frequency of 11 GHz and a fractional bandwidth FBW = 0,0273 is designed using this procedure and presented here as an example. The simulated results by CST are presented and compared withthe results simulated by a high-frequency structure simulator. Good agreement between the simulated HFSSand simulated results by CST is observed.

Opis:
In this paper, the substrate integrated waveguide (SIW) resonator is designed to study the influence of dielectric materials on its operating parameters (insertion loss, fractional bandwidth and unloaded Q-factor). The results obtained show that the use of high permittivity substrate in the SIW resonator by increasing its thickness allows reducing the size of resonator by causing the increase in its unloaded Q-factor. A SIW bandpass filter is designed using low temperature co-fired ceramic (LTCC) technology and high permittivity substrate. The filter has a fractional bandwidth of 27 % centered at 14.32 GHz with insertion loss of 0.7 dB.
