چکیده مقاله:
In this paper, the design and fabrication of theWaveguide Triplexer (WT) model in ۱GHz-۵GHzfrequency bandwidth, with the capability ofdetermination of three frequency bands (first band:۱۷۰۰MHz to ۲۲۰۰MHZ, second band: ۲۶۰۰MHz to۳۱۰۰MHz, and third band: ۳۵۰۰MHZ to ۴۰۰۰MHz) inBand Pass Filter (BPF) structure in the form of aseparate branch for each of the triplexer branches havebeen simulated. The purpose of this investigation is thediminution of return signal losses and improvement ofsignal isolation, as well, as the diminution of signal timedelay in multi-band waveguide triplexer filters. Thetechnical structure of BPF geometry has been designedin the form of rectangular geometry of T-shapedwaveguide, with Regular Transverse Cylindrical Cavity(RTCC) configuration in radiation proportional to Hplaneand E-Plane. One of the other advantages of thisinvestigation is seen in full-wave transmission with theleast signal deviation and weakening. Also, it hasapplications in Automotive Radar Systems (ARS) andTelecommunication-Vehicle Radar (TVR). Thedimensions of the proposed design are ۵.۹۹λ˳*۲.۹ λ˳,the dimensions of which have diminished. The proposeddesign has been simulated in CST Microwave Studio.
