    • 在本論文中，提出了兩種應用於雷達系統上的雙偏極化微帶天線設計。第一種設計在不影響兩端埠隔離度的前提下，可使此天線比單一基本微帶天線增加至少兩倍的頻寬。在第二種設計中，除了能維持相同頻寬，進而也能使此天線在隔離度上有更好的表現。同時論文中也會討論其天線的設計原理並建立一套設計流程。最後為因應雙偏極化系統需求，也研製出一個單刀單擲微波開關。

    In the thesis, two types of designs of dual-polarized aperture-coupled
    microstrip antennas are proposed. In the first design, the bandwidth (for VSWR<2) is increased to at least 2 times of single patch antenna, while the isolation between two ports for different polarization remain the same. In the second design, the performance of both bandwidth and isolation are improved. The thesis also discusses the design theorem and set up the design flow graph of antenna. Finally a single-pole single-throw (SPST) switch is developed for dual-polarized system.
