NOVEL LOW-COST END-WALL MICROSTRIP-TO-WAVEGUIDE SPLITTER TRANSITION

A Broad Bandwidth Suspended Membrane Waveguide to Thinfilm Microstrip Transition

Excellent progress in the development of Submillimeter-wave SIS and HEBmixers has been demonstrated in recent years. At frequencies below 800 GHz these mixers are typically implemented using waveguide techniques, while above 800 GHz quasi-optical (open structure) methods are often used. In many instances though, the use of waveguide components offers certain advantages. For example, broadband c...

W-band Microstrip-to-waveguide Transition Using via Fences

Abstract—The paper presents integrated probe for direct coupling to the WR-10 waveguide with the use of metal filled vias on both sides of the microstrip line. Design and optimization of this novel microstripto-waveguide transition has been performed using 3-D finite element method based software HFSS (High Frequency Structure Simulator). A back-to-back transition has been fabricated and measur...

A New Model for Broadband Waveguide to Microstrip Transition Design

Broadband Millimeter-wave Microstrip Line to Waveguide Transition

Millimeter-wave antennas have been developed for applications of broadband high-speed wireless communication systems and automotive radar systems in these days. Microstrip antennas (MSA) are more advantageous than other millimeter-wave antennas at the viewpoints of low-profile and low-cost. The antenna is connected to the backed RF circuits through the waveguide in the millimeter-wave module as...

Substrate Integrated Waveguide (SIW) to Microstrip Transition at X-Band

Substrate integrated waveguide (SIW) is a new form of transmission line. It facilitates the realization of nonplanar (waveguide based) circuits into planar form for easy integration with other planar (microstrip) circuits and systems. This paper describes the design of an SIW to microstrip transition. The transition is broadband covering the frequency range of 8 – 12GHz. The measured in-band in...
