Synthesis of Transversal Bandpass Filters on Stacked Rectangular $ H$ -Plane Waveguide Cavities

IEEE transactions on microwave theory and techniques, 2019
In this paper, a new transversal configuration is presented for waveguide bandpass filters (BPFs) on stacked rectangular $ H$ -plane waveguide cavities. Different from the conventional ladder BPFs, cavities constituting the proposed transversal BPFs are

Properties of Rectangular Waveguides

1971
For considerations about the propagation of the TM and TE waves derived in Chapter 13 the common factor exp [jωt-Гz] suffices here. The precise form of the electromagnetic field in a given cross-section where z = constant is not relevant in this connection.

Piecewise-uniform bends in rectangular waveguide

IEEE Microwave and Wireless Components Letters, 2005
A new configuration of improved rectangular-waveguide bend for advanced millimeter-wave applications is presented. It consists of few lengths of constant-curvature bends, properly designed in order to obtain enhanced matching conditions, without matching elements.

The miniaturization of rectangular waveguide

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
This paper presented a miniaturization rectangular waveguide which much smaller than hallow rectangular waveguide (HRWG) having same cutoff frequency of dominant mode and a large bandwidth of single dominant mode working (BWSMW) by inserting a suspended dielectric layer which partly covered a metal grounded plane.

Development of Coplanar Waveguide to Rectangular Waveguide Transition

2009 Annual IEEE India Conference, 2009
This paper deals with a transition between CPW and rectangular waveguide suitable in phased array antenna environment. In case of phased array antenna where the scan angles are very large, the sub array size gets reduced. Hence in such cases the feed element size becomes very small and the accommodation of active module comprising phase shifter and ...

Rectangular waveguide impedance

13th International Crimean Conference Microwave and Telecommunication Technology, 2003. CriMiCo 2003., 2003
Presented in this paper is the analytical dependence of H/sub 10/ wave impedance on parameters b/a and a//spl lambda/ for the waveguide with cross-section a/spl times/b. For the given value a//spl lambda/, the function Zg(b/a) can be approximated by function A(b/a)Zc/sub 10/(b/a), where constant A possesses values from 0,5 up to 2 over the waveguide ...

Rectangular waveguide devices

1987
The general theory of transversely magnetised ferrite in rectangular waveguide is given in Chapter 6. In particular, Fig. 6.1 shows the planes where the magnetic field in the rectangular waveguide is circularly polarised in a plane parallel to the broad face of the waveguide.

Ground coplanar waveguide to rectangular waveguide transition

2009 IEEE Antennas and Propagation Society International Symposium, 2009
The ever-increasing interest towards microwave and millimeter-wave monolithic integrated circuits has led to employing coplanar waveguide (CPW) due to its many advantages such as compact size and capability to incorporate shunt and series elements without the need to process backside and integrate via holes.

Investigation of Ridge-Loaded Folded Rectangular Groove Waveguide Slow-Wave Structure for High-Power Terahertz TWT

IEEE Transactions on Electron Devices, 2018
A novel slow-wave structure (SWS) called ridge-loaded folded rectangular groove waveguide has been proposed for developing the wideband high-power terahertz (THz) traveling-wave tube (TWT).
