A Novel Dual Band Branch Line Coupler and its Application to Design a Dual Band 4 × 4 Butler Matrix
A novel dual band branch line coupler (BLC) has been proposed, designed, implemented, and analyzed in this paper. A dual band 4 $\times 4$ Butler matrix (BM) has also been developed by employing the proposed BLC. To realize the proposed BLC, PI and modified PI-shaped transmission lines (TLs) as dual...
