“…For high Q-factor and low-loss BPFs, air-filled metal-pipe rectangular waveguide or gap waveguide technologies can be adopted. In recent years, many waveguide-and gap waveguide-based mm-wave BPFs have been fabricated using machining technology, by milling out or drilling into metal structures [2], [19]- [21], [32] and [33]. Machining technology is preferred for high-Q and low-loss components within the mm-wave band.…”

“…For high frequency microwave/mm-wave applications, designers prefer metalpipe rectangular waveguide solutions, due to their low loss and high power handling capabilities. Typical examples of waveguide BPF implementations have been demonstrated at X-band (8.2-12.4 GHz) [1] and Ku-band [2]. One of the drawbacks with conventional waveguide components is the poor electrical contact between joined waveguide parts, especially at mm-wave frequencies.…”

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.
