Wearable Substrate Integrated Waveguide (SIW) Iris Band Pass Filter (BPF) over Jeans Substrate

This paper explores the designing technique of body wearable iris band pass filters over substrate integrated waveguide (SIW) by opting jeans as a substrate material with relative permittivity of 2.72, thickness 2mm and dielectric loss tangent of 0.002. Simple microstrip to SIW feeding technique is used for impedance transition. A number of iris configurations are studied and presented with simulated outcomes. All configurations are compared and presented with vital filter characteristics. The filters have been developed targeting body wearable trans-receiving systems in microwave X-bands in terrains where installation of bulky components produces transport challenges. All simulations are carried over Ansoft HFSS
