“…Similar to the 60 GHz (V-band) LTCC filters reported in [5][6][7][8][9], the insertion loss of the proposed filter highly depends on the dielectric loss of LTCC substrates. This is because the incident wave must penetrate the LTCC substrate to excite the stacked SIW cavities.…”

This study presents a 60 GHz quasi-elliptic bandpass filter with a compact and planar structure. The proposed filter was constructed by stacking substrate integrated waveguide (SIW) cavities on the central transverse plane of a shielding SIW cavity. Jerusalem cross (JC) apertures and circular apertures were etched on the metal layers of the stacked SIW cavities to enable dual-mode operation and energy coupling. In the dual-mode cavities, the TM 110 cavity mode and JC aperture mode can be excited simultaneously. Cross-mutual couplings exist among the resonant modes, resulting in two finite transmission zeros with each at either side of the passband. Multilayer low-temperature cofired ceramic technology was adopted to manufacture the experimental filter. The measured centre frequency was 60 GHz at a fractional bandwidth of 4.5% with two finite transmission zeros located at 53.7 and 65 GHz, thereby achieving highfrequency selectivity.

“…Low temperature co-fired ceramic (LTCC) technology, with sintering below 1,000 • C, is used to produce compact multilayer circuits. LTCC has been used to implement different mm-wave BPFs; for example, planar-based filter of 60 GHz [25], [26] and SIW-based filter at 40 GHz [5], 140 GHz [27], [28] and 174 GHz [29]. LTCC technology has many advantages for the manufacture of microwave BPFs.…”

Lightweight and Low-Loss 3-D Printed Millimeter-Wave Bandpass Filter Based on Gap-Waveguide

This paper presents a comprehensive study of a groove gap waveguide (also known as a waffle-iron) bandpass filter at Ka-band (26.5-40 GHz), fabricated using a high resolution polymer jetting (Polyjet) 3-D printing technology. The same filter was previously fabricated using brass CNC milling technology. The metalized Polyjet 3-D printed filter has lower loss, is lighter in weight and more costeffective, when compared to the solid metal case. The filter operates at a center frequency of 35.65 GHz, has a 500 MHz bandwidth (1.4% fractional bandwidth), and has a transmission zero below and above the passband. Without any design iterations, the measured S-parameters for the Polyjet 3-D printed filter are presented and compared with simulated results, showing excellent agreement. A comparison is then made between the measured results and that of its brass machined counterpart. The new Polyjet 3-D printed filter is 85% lighter than the conventional machined version. All these features prove the important potential of 3-D printing technology for millimeter-wave applications, which includes aerospace.

“…Due to their very good electrical properties at very high frequency, benzocyclobutene (BCB) and liquid crystal polymer (LCP) are also considered by some authors. In References [9,10], Ku-band SIW BCB filters with embedded silicon vias and K-band LCP SIW filters, respectively, are presented. However, despite interesting performances, these solutions use planar substrates with low thickness between 100 and 400 µm, leading to limited quality factors.…”

LDS Realization of High-Q SIW Millimeter Wave Filters with Cyclo-Olefin Polymers

In this paper, we present narrow-band substrate integrated waveguide (SIW) millimeter wave band-pass filters, designed using cyclo-olefin polymers (COP). The structures were molded, drilled, and metalized with a laser direct structuring (LDS) process. COP are a type of thermoplastic with low dielectric losses in the millimeter waveband, typically 7.5 × 10−4 at 40 GHz for the COP RS420-LDS from Zeon®. The body of the filter was realized using a molding process that facilitates the combination of thin 50 Ω microstrip access lines with high thickness microwave cavities through 3D transitions, thus making high quality factors attainable. The simulations and experimental results are presented and discussed.
