Summary: 
Non-equal length, three section coupled transmission line couplers are proposed. The proposed structure offers increased design flexibility and the compact circuit design capability over the conventional quarterwave coupled lines. The detailed analysis results and design method are presented along with the numerical and the experimental verification.
