“…A 4-pole dual-mode resonator filter on LTCC for 30 GHz center frequency with FBW of 4.67% and an insertion loss of 2.95 dB using two transmission zeros is reported on a five-metal layer stackup in [59]. Similarly, two-pole, twostage SIW single cavity filter with embedded planar resonators realized on five layers of LTCC with center frequency of 28.12 GHz, 15% FBW and 0.53 dB insertion loss is reported for 5G applications in [60]. A four-pole, four-cavity SIW filter with 2.66 dB insertion loss at the center frequency of 27.45 GHz with 3.6% FBW is designed on nine layers of LTCC in [61].…”

Increasing data rates, spectrum efficiency and energy efficiency have been driving major advances in the design and hardware integration of RF communication networks. In order to meet the data rate and efficiency metrics, 5G networks have emerged as a follow-on to 4G, and projected to have 100X higher wireless date rates and 100X lower latency than those with current 4G networks. Major challenges arise in the packaging of radio-frequency front-end modules because of the stringent low signal-loss requirements in the millimeter-wave frequency bands, and precision-impedance designs with smaller footprints and thickness. Heterogeneous integration in 3D ultra-thin packages with higher component densities and performance than with the existing 2D packages is needed to realize such 5G systems. This paper reviews the key building blocks of 5G systems and the underlying advances in packaging technologies to realize them.

“…7(b). However, further investigations on the fabrication process are needed to improve the performance of the filter for single and multiple-mode filter based on substrate integrated circular cavity using Low Temperature Co-fired Ceramics (LTCC) [17]. This method is seen as a good solution for compact size filters and to improve the insertion loss.…”

A substrate integrated waveguide circular cavity (SIWCC) bandpass filter is developed using printed circuit board technology. A circular cavity structure using TM 110 mode was employed in the design of the filter to operate at the frequency of 4.75 GHz, which is in the C-band frequency range. The filter was designed based on double-layer elements comprising a substrate integrated circular cavity (SICC) and a transmission line (TL) that produce single-mode resonance. In the proposed structure, circular resonators consisting of vias and a rectangular patch at the top layer are combined into a circular substrate integrated waveguide (SIW) structure. To achieve the desired resonance frequency, a triangle probe is etched at both sides of the microstrip line feeding section. The proposed structure is put in a conducting box to prevent radiation to the outside and eliminate radiation loss. Furthermore, the desired centre frequency and bandwidths of the passbands can be obtained by adjusting the dimension of the filter. To prove the concept, the filter structure is fabricated using Rogers RO4350B TM circuit materials with a dielectric constant of ε r = 3.48 and height of the substrate of 1.52 mm. The design was simulated using Ansoft HFSS simulator and measured using a vector network analyser. Simulation and fabrication results are compared for verification. The proposed SIWCC bandpass filter has potential applications in satellites and wireless communication systems.
