A new method for determining the propagation constant and the effective width of Substrate Integrated Waveguides (SIWs) is presented in this paper. SIW cells can be viewed as two consecutive rectangular waveguide with same height but different width...

Based on the theory of multi-hole waveguide directional couplers, an X-band multi-hole directional coupler with a folded substrate-integrated waveguide has been designed and fabricated. Simulation results show that the proposed coupler has isolation...

Two types of antennas based on the open-ended substrate integrated waveguide (SIW) resonator are presented and investigated in this study. To understand the operation mechanism of these antennas, the open-ended SIW resonator is analysed by two...

In this paper a new low profile, substrate integrated

introduced. In order to suppress parasitic radiation and to

reduce conductor loss of the ...

In this paper new antennas using an open-ended substrate integrated waveguide (SIW) resonator are presented. The open-ended SIW resonator is analyzed using two different approaches. In the first approach we use the waveguide theory and in the second...

In this letter, a simple approach for design and realization of dual mode substrate integrated waveguide (SIW) bandpass filter of order higher than two is presented. The dual mode resonators are square SIW cavities perturbed by corner cut...

This article presents two new cavity-backed slot antennas utilizing substrate-integrated waveguide technology and offering high gain. Radiation performances of the proposed antennas are experimentally and numerically evaluated. Using two slots...

A new and accurate closed-form expression is introduced using least squares method (LSM) to
