## Abstract In this article, an extremely compact dualβband branchβline coupler is presented. The miniaturized design saved 74% circuit dimension comparing to the original dualβband branchβline coupler. Several design methods and miniaturization techniques were involved in this study to achieve the
## Abstract A compact wideband monopolar patch antenna, which is resonated by a multioperating structure, is presented. The multioperating structured antenna is constructed by a crossshape copper plate folded as an upward cap, excited by a square disc coupling feed. Without the folded upward wall,
