“…Microwave hybrid is one of the essential components in many wireless applications, and used in microwave circuits and advanced antennas such as phase shifters [1], balanced mixers [2,3], power dividers [4,5] and beam steering antennas [6,7,8,9,10,11,12]. Magic-Ts are well known as a 180 • hybrid, which acts as an in-phase/anti-phase power combiner/divider.…”

This letter proposes a novel planar magic-T employing microstrip lines and a coplanar stripline (CPS) integrating a microstrip-to-CPS transition. The proposed magic-T uses a CPS instead of the slot line used in conventional planar magic-Ts to reduce the radiation loss. Defected ground structures (DGSs) are also used to suppress undesired common modes. This circuit has several attractive advantages in comparison with the conventional similar designs such as excellent amplitude and phase performance, compactness, and widely useable structure using a microstripto-CPS transition. The design, analysis and prototype parameters are discussed, followed by the measured and simulated results of the proposed magic-T.
