摘要

An extended works of a diamond shaped 3 dB coupler design that is operating in ultra-wideband frequency range is presented in this article. The proposed design is accomplished by using multilayer technology in which the structure is formed by three layers of conductors and interleaved by a layer of substrate between each one of the conductor layer. The proposed designed coupler simulation result shows that the design exhibits a coupling of 3 dB return loss and isolation better than 22 and 21 dB, respectively. Whereas, the phase difference performance is in the range of 90°±2° over the designated band. The coupler is fabricated and measured. Analysis studies on the parametric value are presented and discussed to observe the effect of the dimension of the patch to the performance of the coupler.
