Design of reconfigurable integrated substrate integrated waveguide (SIW) filter and antenna using multilayer approach

摘要

This article presents an integrated technique for reconfigurable substrate integratedwaveguide (SIW) and reconfigurable patch antenna by using the varactor diodes. Areconfigurable SIW filter and reconfigurable patch antenna were integrated usingthe multilayer technique into a single structure in order to realize the integrationtechnique. Design and validation of an equivalent circuit with the varactor diode ispresented to study the tunable mechanism. A good performance between thesimulated and measured results was achieved. This proposed structure of the reconfigurableintegrated SIW filter and antenna is useful for wireless communicationsystems especially in telecommunication technology.
