摘要：
The mixed-potential integral equation (MPIE) is solved by the method of moments in order to investigate arbitrarily-shaped slot-coupled microstrip discontinuity problems. A concise expression of the mutual coupling matrix element is utilized to assure numerical efficiency and accuracy. Comparison between this MPIE and other moment methods (such as MFIE and EFIE) is also carried out and discussed. In order to validate this modeling tool, a circularly polarized dual slot-coupled patch antenna and a single slot-coupled directional coupler are investigated. Good agreement between numerical results and measurement is achieved. Two examples of dual slot-coupled patch antenna and annular ring slot antenna with microstrip line feed are designed to provide desired circularly polarized radiation. In addition, a weak coupling slot-coupled directional coupler is designed by utilizing a pair of circular slots. Good performance for directivity, isolation, and return loss is obtained.
