Abstract
The main goal of this project is to start from first principles and design broadband Microstrip Balun circuits, at a center frequency of 5 GHz, for wireless applications. Typically, design of broadband multi-section couplers is limited to odd order structures. However, the current work is in a newer direction with even order design specification, which required us to start from fundamental multi-section theory. Starting with fundamental theory, we arrived at 2 and 4 section wideband balun designs, which show good amplitude and phase balance. The fabrication of the balun structures that were designed in this work will be carried out in the next continuing project by future graduate students.
