Abstract :
This letter presents a broadband half mode substrate integrated waveguide (HMSIW) attenuator. A resistive π-network was built on the HMSIW structure to achieve respective target attenuation levels (1 dB, 2 dB, 3 dB, 4 dB, and 5 dB), where this network is comprised of a set of surface mount technology (SMT) passive resistors. The five different prototypes per attenuation level were evaluated (1-5 dB, 1 dB step) in a band of 7.29-14.9 GHz, and each prototype´s simulation and measurement meet the good agreement.
