“…We have used an 80μm SiC substrate (ε r = 9.9) which was fabricated by our in house process at Chalmers. The total substrate size is 2×1.75 mm 2 and on this substrate a microstrip line with two probes has been printed. The prototype has been measured with Agilent PNA (N522A) and Agilent extender modules (N5260-6003).…”

“…Several kinds of microstrip-towaveguide transitions have been proposed in the millimeter-wave band recently. E-plane probe transitions [1][2][3], vertical transitions [4] and the inline transitions with stepped waveguide height [5,6] are the most popular ones. Among these, the E-plane probe has been used extensively due to wideband performance and modular simplicity.…”

Abstract-This paper presents a unique low loss transition from microstrip to full height rectangular waveguide at W-band. This microstrip transition can be made as a part of the mm-wave MMIC of arbitrary size and thus avoid the use of bond wires at the high frequency port of the MMIC circuit. As a result, the MMIC can be coupled directly to the waveguide. The working principle of the transition is based on electromagnetic coupling where the coupling between the microstrip mode and the TE 10 waveguide mode is achieved via a resonant cavity. A Perfect Magnetic Conductor (PMC) surface is placed over the cavity to facilitate smooth coupling of EM energy from the microstrip line to the cavity and then from the cavity to the waveguide. The PMC surface also suppresses the unwanted waveguide mode coupling to the oversized MMIC substrate. The measured back to back transition works over the frequency band 80-114 GHz (relative BW of 35%) with minimum return loss of 13.5dB. The total insertion loss of the manufactured prototype is found to be varying from 0.54-0.803 dB which implies a single transition loss of less than 0.27-0.4015 dB in W-band.

“…The most popular microstrip-to-waveguide transition consists of a probe placed in the E-plane of the waveguide [6,8]. In particular, some transitions of this type have been presented operating in the full W-Band such as those proposed in [7] and [8] obtaining experimentally good return and insertion losses.…”

An inline microstrip-to-waveguide transition covering the full W-Band is presented in this article. The verification of the simulation results has been carried out by means of a back-to-back transition measurement. Experimental results show good return losses above 15 dB in the entire W-Band and also low insertion losses. Specifically, the measured insertion losses are 0.71 dB at the central frequency of W-Band, i.e., 92.5 GHz, and below 1.1 dB in the full W-band.

An inline waveguide‐to‐microstrip transition for wideband millimeter‐wave applications

A low‐cost wide Ka‐band inline waveguide‐to‐microstrip transition is proposed, which facilities the integration of planar transmission lines with waveguide structures. By employing a circular patch above a wedge‐shaped cavity, the quasi‐TEM mode wave in the microstrip line can be transformed into the TE10 mode wave in the rectangular waveguide. A transition prototype in a back‐to‐back configuration is manufactured and experimentally tested. Measured results show that the return loss is greater than 13 dB from 28 to 38 GHz and the insertion loss remains less than 0.4 dB for the proposed single‐side transition. With the features of wideband, compact structure and easy integration, the proposed transition can be applied in the low‐loss and high‐integration millimeter‐wave systems.
