A compact high-efficiency four-way divider/combiner based on quadruple-ridged waveguide is presented. This divider/combiner designed at 31-38 GHz is mainly composed of the quadruple-ridged transition, which features four-way power divider/combiner as well as transition from waveguide to microstrip. The measured power-combining efficiency of this circuit at 34 GHz is up to 91%, and the combining efficiency is higher than 80% at 31-38 GHz.

“…The power combiner/divider is an essential passive component in modern microwave communication systems. The Wilkinson PCD is a popular structure [1][2][3][4][5]. The current research mainly focuses on improving the isolation or bandwidth of the Wilkinson PCD [6][7][8][9][10], and there is less research on the improvement of the powerhandling capability of the Wilkinson PCD.…”

A Wilkinson power divider/combiner with enhanced power-handling capability

Fang

et al. 2022

This letter proposed a new Wilkinson power combiner/divider (PCD) with enhanced average power-handling capability (APHC) by decreasing the impedance of the microstrip of the combine port. For verification, one example of the proposed Wilkinson PCD operating at 2.3 GHz was designed, fabricated and measured to verify the proposed theory. One traditional Wilkinson PCD operating at 2.3 GHz was also fabricated to compare the APHC of the proposed Wilkinson PCD and the traditional Wilkinson PCD, by means of measuring the temperature variation of the microstrip line at the same input power. The measurement result of the temperature variation suggests the APHC of the proposed Wilkinson PCD is nearly twice that of the traditional Wilkinson PCD.

“…Based on those advantages, there are many applications of SIW in filters, power dividers, couplers and antennas and one hot topic is the slot array antenna. Some of them may even have electrical properties comparable to conventional metal waveguides [1,2,3,4]. As the growing applications in using the SIW to electronic systems, SIW higher order mode components are attracting more and more research interests.…”

Higher mode SIW excitation technology and its array application

et al. 2017

An excitation technology of TE 40 mode for substrate integrated waveguide (SIW) and its application in designing a slot antenna array is proposed. In order to excite the TE 40 mode, a microstrip power divider and two coupling slots driven by microstrip lines in the longitudinal direction of SIW are designed to convert the electromagnetic field pattern from slot lines to SIW. The advantages of the TE 40 mode are not only reducing process complexity but also simplifying the feeding network so as to reduce the production bottlenecks at high frequency. A 16-element slot array antenna fed by the TE 40 mode SIW is designed based on the standing wave antenna array principle. Experimental results show that a 4×4 antenna array fed by TE 40 mode achieves a maximum radiation gain of 15.2 dBi and 85% radiation efficiency at 10.4 GHz and an impedance bandwidth ranging from 9.95 to 10.6 GHz with |S 11 | below −10 dB. The achieved results demonstrate the superiority of the higher mode excitation technology and it is reasonable to deduce that other higher modes can be achieved based on the proposed technology.
