| dc.description.abstract | With the increase of global data traffic every year, the demand for high-speed connectivity is getting stronger day by day. Microwave technology for wireless communication is a strong contender for high-speed, low-latency communication. These high frequency transmission links have tiny cavity filters with complex geometry, which is arduous to manufacture with the conventional methods. This calls for novel alternative manufacturing technologies to produce these filters without compromising the performance. The thesis explores the feasibility of employing additive manufacturing techniques called binder jetting (BJT) and Material Jetting (MJT) for the manufacturing of the tiny intricate cavity resonators for 23GHz, 80GHz, and 110GHz respectively. The resonators were manufactured by Bosch using Markforged PX100™ BJT printer and XJET Caramel 1400M MJT printer with different orientations to study electrical performance and how dimensional accuracy and surface roughness affect the performance of the printed parts. The print job for the BJT was carried out in two batches, second print was carried out after making the design changes from the feedback of the first print. The first design presents itself with sharp edges and corners while the second one incorporates fillets. The design change has brought difference in the results as well, the first print showed a close resonant frequency with less output signal while the second print with fillets shows a shift in anticipated frequency but with improved output signal. MJT parts reproduced the designed resonant frequency with superior surface finish and dimensional accuracy. It is unclear that the different orientations have effect on the performance of the resonator. | |
