TMTT Paper Acceptance for Basem Abdelaziz
Basem's paper titled "An Ultra-Compact and Wideband Transformer-Based Coupler with Arbitrary Phase Difference and Arbitrary Power Division Ratio" has been accepted to the Transactions on Microwave Theory and Techniques Journal.
In this work, we propose a wideband ultra-compact transformer-based lumped coupler that offers an arbitrary phase difference and power division ratio between the two output ports, while maintaining input/output matching and isolation conditions. It achieves at least 14x smaller size compared to previously reported transmission-line/coupled-line implementations and around 15-20% larger fractional bandwidth compared to previously reported lumped coupler implementations.
