Abstract: The Continuous Transverse Stub (CTS) antenna is implemented with an array of continuous transverse radiating stubs extending from the upper conductive plate of an open parallel-plate transmission-line structure, and internally excited by a TEM mode linear source. It is an important topic for high gain antennas due to its high radiation efficiency and aperture efficiency. CTS array is also convenient for beam-controlling and dual-polarizations application and has the advantages of ease fabrication and low cost, which promise its broad application prospects. In this dissertation, design on planar CTS arrays and low-loss TEM mode linear sources are investigated as follows. First, the radiation mechanism of CTS element is analyzed; second, an element model with periodic boundary is established to conduct simulation on the relationship between structure parameters and radiation performances of CTS element. In this dissertation, antenna structure combining SIW and CTS segment is presented. After a literature review and introduction of antenna fundamentals, the study focuses on two types of SIW-CTS antennas, namely, 8-element SIW-CTS antenna and 4-element SIW-CTS antenna with rectangular ridges. This study includes theoretical analysis, computer-aided design by the commercial software HFSS. By the feed of coaxial and under operating frequency I OGHz, the 8-element SIW-CTS antenna obtains 7.6% bandwidth and 45% aperture efficiency, while the 4-element SIW-CTS antenna obtains a 78% aperture efficiency and 2% bandwidth.
