RISDevelopment of a Low Profile and Wideband Backward-Wave Directional Coupler Using Neural Network
In this paper, a low profile and wideband backward-wave directional coupler is introduced. It
operates similar to the composite right left handed (CRLH) couplers. Two different mechanisms including
connections between the coupled...

Development of Forward-wave Directional Couplers Loaded by Periodic Shunt Shorted Stubs
In this paper a new procedure for designing forward-wave directional couplers using periodic shunt
short circuited stubs is proposed. A new type of cell using these stubs, which enlarge the pahse
difference between even- and odd modes...
Development of broadband forward-wave directional couplers loaded by periodic patterned ground structure
In this paper two wideband Forward-Wave Directional Couplers (FWDCs) with 0 dB and 3 dB coupling level are proposed. Using periodic patterned ground structure in a microstrip coupled lines by a new unit cell; even- and odd-mode characteristic...
A New Method to Improve Directivity Bandwidth of Directiional Coupler
In this paper a new technique is proposed to improve the directivity and directivity bandwidth of couplers. In this approach, a low pass filter has been inserted before isolation port. It is shown that this technique can ...
Development of a Forward-Wave Directional Coupler Loaded with a Periodic Shunt Structure
The current paper presents a wideband forward-wave directional coupler. Periodic shunt structure is employed to design the proposed coupler. Using even- and odd-mode analysis, it is shown that even- and odd-mode characteristic impedances are equal...
