Objectives

Objective 1: Investigation of the actual features of the novel tuning elements described at the concept level in a pending patent [1]. This step is essential to conduct successfully the research activities towards the achievement of the second, main objective, since the tuning elements’ novelty asks for a specific theoretical support. Therefore, consistent models of the tuning element’s basic parts (air-filled hole within SIW dielectric, and tuning rod surrounded by an air ring) have to be build up for accurate prediction of their properties. Advanced electromagnetic simulations and experimental verifications will permit the models’ validation and enhancement.

Objective 2: Design, manufacturing and complete characterization of a laboratory-grade SIW band-pass filter (BPF), provided with the novel mechanical tuning elements described in [1] for both coarse and fine tuning, and optimization of its characteristics.

The SIW filter will operate over a frequency sub-band within 5.15 - 5.725 GHz range, specific to short range wireless communication application. Confirmation of the tuning elements’ capacity to improve the RF parameters of the BPF will represent the ultimate validation of the concept.
