In this paper, a novel microwave planar integration scheme is proposed based on SIW technology. All the passive components in RF transceiver are implemented using SIW, including antenna, duplexer, TX/RX filters and LO power divider. A demonstration X-band transceiver is designed in a single layer printed circuit board. The design of SIW components and RF/IF circuits are discussed, as well as various...
In this paper, a planar triplexer based on the substrate integrated waveguide (SIW) technology for TD-SCDMA applications is proposed. The triplexer consists of three inductive window SIW bandpass filters, operated at bands of 1.88GHz-1.92GHz, 2.01GHz-2.025GHz and 2.3GHz-2.4GHz, respectively, and an optimized matching circuit. Moreover, by introducing a stepped-impedance microstrip lowpass filter,...
In this paper, a broadband compensating phase shifter is presented based on the substrate integrated waveguide (SIW) technology. The SIW is a dispersive guided-wave structure, but the phase shifts generated by two different structures (the delay line and the equal-length unequal-width phase shifter) have just reverse varying tendencies versus frequency. Thus, the complementing combination of them...
In this paper, the substrate integrated waveguide (SIW) is investigated into the effects of tolerances using the sensitivity approach. The changes in characteristics of transmission line due to the tolerances of its parameters have been analyzed to evaluate the worst case behavior. A set of sensitivity curves are given to help the design procedure and used to determine the tradeoff between performances...
With merits of low loss and highly integration, substrate integrated waveguide (SIW) has been widely used in the designs of modern microwave and millimeter circuits. However it suffers from the big size in low microwave band. Recently, a novel half mode substrate integrated waveguide (HMSIW) has been proposed, which keeps the good performance of SIW with a nearly 50% reduction in size. So far, no...
