Compact miniaturized half-mode waveguide/high pass-filter design based on SIW technology screens transmit-IEEE C-band signals

In this article, a novel compact structure with a compact size and low insertion loss half-mode substrate integrated waveguide/high pass-filter dedicated for microwave signal guiding and high signal filtering that screen transmit-IEEE C-band signals is optimized, fabricated, and measured. The measurements results of the S parameters are compared with those provided by the commercial software CST Microwave Studio. Agreements between measurements data and the CST software results were achieved. It numerically compares how the transmission in C-band can be successfully achieved with HMSIW. The Half-Mode SIW Waveguide/High Pass-Filter design size achieved is 7.5 x 35 mm(2). A size reduction of about 50% in comparison with a similar SIW Waveguide/High Pass-Filter has been achieved. The measured insertion loss is below -2 dB while the return loss is less than 10 dB. It is attractive which can be used for the radio communication system applications.
