Broadband stripline to rectangular waveguide transition

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...

Rectangular Waveguide to Coax Transition Design

question I am frequently asked is, “Why do the antenna dimensions in the W1GHZ Microwave Antenna Book — Online not include the probe dimensions (for the transition from waveguide to coaxial transmission line)?” The answer is that the transition is part of the transmission line, not the antenna, and does not directly affect the performance of an antenna. The transition may be right at the antenn...

A Broadband CPW-to-Waveguide Transition Using Quasi-Yagi Antenna

A novel CPW-to-waveguide transition utilizing a uniplanar quasi-Yagi antenna is presented. The X-band back-to-back transition demonstrates 33% bandwidth with return loss better than -10dB. This transition should find a wide variety of applications due to its high MIC/MMIC compatibility and low cost.

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...
