Nowadays, microwave systems have gained more interest in wireless communications due to the need both for higher data rates and greater bandwidth. Nevertheless, electromagnetic compatibility (EMC) problems on circuit components is one of the significant problems to be overcome in these systems. High electromagnetic isolation must be ensured in neighboring microwave circuits or between critical components and undesirable electromagnetic interference (EMI) must be suppressed. Recently, new structures that the microwave circuits are located in metal enclosures containing three-dimensional periodic metal pin arrays called as perfect magnetic conductor (PMC) packaging are proposed to solve these problems. In this study six different novel pin geometries as helical shaped models containing one, two, three and four helices, pyramidal shaped model and inverted pyramidal shaped model are suggested. Pinned cover models are designed with all proposed pin shapes and the obtained simulation results are represented by comparing with the square cross-sectioned ones. The band gap of the stop band region obtained by the proposed pinned covers are shifted to the lower frequencies according to the band gap of the pinned cover with square cross-sectioned pins. The suggested pin geometries can contribute to the compactness of the covers by their lighter, smaller and requiring less material features. |
