PCB antenna design for real world environments

Published on 12, Feb

It is easy to find appnotes with PCB antenna examples, but copying an existing design to your own PCB can result in disappointing performance. In this document, we will have a look at some of these external influences, and their effect on antenna performance. PCB antenna design for real world environments

28GHz RFIC inductor performance vs. ground cutout size

Published on 9, Aug

When I published the appnote on filler and ground effect for a 60GHz balun, there were many comments and questions on the ground cutout. It seems that many designers didn’t realize the possible loss in performance from a ground cutout that is too small. That’s enough reason to adress the issue and a possible solution […]
