In this paper, compact substrate integrated waveguide (SIW) power dividers with equal and unequal power divisions are considered. But, the main advantage of the power dividers is their compact sizes.Abstract:
In this letter, compact substrate integrated waveguide (SIW) power dividers are presented. Both equal and unequal power divisions are considered. A quarter-wavelength long wedge shape SIW structure is used for the power division. Direct coaxial feed is used for the input port and SIW-to-microstrip transitions are used for the output ports. Four-way equal, unequal and an eight-way equal division power dividers are presented. The four-way and the eight-way power dividers provide −10 dB input matching bandwidth of 39.3% and 13%, respectively, at the design frequency $\text {f}_{0}= 2.4$ GHz. The main advantage of the power dividers is their compact sizes. Including the microstrip to SIW transitions, size is reduced by at least 46% compared to other reported miniaturized SIW power dividers.read more

TL;DR: In this article, a new method of analysis is presented for the determination of complex propagation constants in substrate integrated waveguides (SIWs) by making use of the concept of surface impedance to model the rows of conducting cylinders, and the proposed model is then solved by combining a method of moments and a transverse resonance procedure.
