Abstract :
A new uniplanar de Ronde´s CPW-slot directional coupler was developed with good amplitude characteristics and phase balance. The even-odd mode analysis of four-port networks with double symmetry was used to analyze the uniplanar de Ronde´s couplers. A directional coupler with 5-dB coupling was designed and demonstrated over the frequency range of 2.4-3.4 GHz. The experimental results agree with the theoretical design.<>
