Analysis and design of post-wall waveguides for applications in SIW

Analysis of S-Band Substrate Integrated Waveguide Power Divider, Circulator and Coupler

“…The power dividers [16] are commonly used to deliver copies of a signal in a system, there are mainly two types T and Y [14] [15]. Our study focuses on the three ports power dividers with equal power division ratio where the half power (-3 dB) of an input signal is provided to each of the two output ports, its S matrix is shown in equation (6) […”

“…The RSIW directional coupler (-3 dB) ( Figure 14) is realized by two RSIW with a common wall on which an aperture is utilized to realize the coupling between these two guides. The geometry of the coupler [15] is based on an even/odd mode analysis, where β and β are the propagation constants of the TE 10 and TE 20 modes, respectively. The phase difference ∆φ (7) ∆φ = (β -β )W…”

Design of V-Band Substrate Integrated Waveguide Power Divider, Circulator and Coupler

“…The RSIW directional coupler (-3 dB) is realized by two RSIW with a common wall on which an aperture is utilized to realize the coupling between these two guides. The geometry of the coupler is determined [15] based on an even/odd mode analysis, where the even mode is the TE 10 and the odd mode is the TE 20 . The phase difference ∆φ between the two modes is expressed by…”

An electromagnetic model for post-wall waveguide building blocks

“…The main disadvantages of this approach are its inability to handle losses, or equivalently, complex propagation constants, and to handle more complex PWWG components, such as those described in [5]. In recent years [6], we have introduced an alternative approach for handling PWWG components that overcomes both limitations. In this paper we present a brief overview of this approach and we discuss preliminary simulation results.…”
