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...

Broadband Transition from Microstrip Line to Waveguide Using a Radial Probe and Extended GND Planes for Millimeter-Wave Applications

A broadband microstrip line-to-waveguide (MSL-to-WG) transition is developed for E-band applications. In order to achieve a sufficient and broadband coupling between the microstrip line (MSL) and waveguide (WG), a radial electric probe at the end of the MSL and extended ground (GND) planes on the dielectric substrate are proposed. Results are compared against a simple transition (S-Tr) with a s...

Broadband Rectangular Waveguide to GCPW Transition

A broadband transition design between rectangular waveguide and GCPW is proposed and studied. The E-field of GCPW is designed to be gradually changed to that of waveguide via the simple tapered probes and metallic vias. The planar circuit of the transition is fabricated by low cost standard PCB process. The tolerance analysis for this transition is also given. A back-to-back transition prototyp...

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...
