[Abstract]:With the development of wireless communication system, the demand for miniaturization, low-cost and multi-function equipment is increasing. Microwave filter is one of the most important devices in RF front end of communication system. Substrate integrated waveguide (SIW), a new guided wave structure, has been widely used because of its high quality factor, large power capacity, small size and easy processing. The half-mode substrate integrated waveguide (HMSIW) reduces the size of SIW by half, which makes it more and more active and passive devices such as filters, duplexers, antennas, oscillators and so on. In this paper, several high performance and miniaturized HMSIW bandpass filters are studied and implemented, and a novel slow wave half-mode substrate integrated waveguide structure is proposed, and its transmission characteristics and design methods are studied. The research work includes the following aspects: firstly, this paper introduces the basic structure and transmission characteristics of HMSIW, including its transmission mode, design principle and conversion structure. At the same time, the traditional HMSIW band-pass filter is mainly the extraction method of external Q value and coupling coefficient of inductive metal hole coupling band-pass filter, and the concrete design method of this kind of filter is summarized. Secondly, two new miniaturized HMSIW bandpass filters are designed: one is a balanced ultra-wideband HMSIW filter with DGS structure introduced into the differential HMSIW transmission line; The other is a CSR-based HMSIW dual-pass band filter with different sizes of CSRR on the upper and lower surfaces of the HMSIW structure. The design method and implementation process of the two filters are introduced in detail. The simulation and test results agree well with each other and verify the correctness of the design method and theory. Finally, a new slow wave half-mode substrate integrated waveguide structure is proposed, which is a miniaturized HMSIW structure based on the structure of the slow wave substrate integrated waveguide. The transmission characteristics are analyzed in this paper. At the same time, a notch band filter based on SW-HMSIW is designed. The accuracy of the design is verified by the simulation of S parameters and the processing test.
