This article proposes a low-loss and light 3D-printed substrate-integrated waveguide (SIW). Despite the use of lossy polylactic acid (PLA) material, insertion loss is reduced, and bandwidth is increased due to a honeycomb substrate similar to air. To demonstrate the proposed concept, we fabricated microstrip-fed SIWs with solid PLA and honeycomb substrates, and compared their performance numerically and experimentally. Average measured insertion loss from 3.4 to 5.5 GHz for the honeycomb SIW is 1.38 dB, whereas SIW with solid PLA is 3.15 dB. Light weight is an additional advantage of the proposed structure.

“…In (8), H t takes into account the contribution of all higher order modes in the PPWs and the mutual coupling among feeding waveguides (see (5)). In (9) M t, TEM considers only the effect of the fundamental mode within the PPWs.…”

“…They consist of arrays of stubs or openended parallel-plate waveguides (PPWs), which radiate in free space and may be fed either in series or in parallel. A seriesfed CTS array [5] comprises stubs, finite in height, placed on the upper plate of a PPW. The beam is spatially steered by varying the angle of incidence of the wave launched into the feeding PPW.…”

This paper presents an efficient analysis method for a novel continuous transverse stub (CTS) antenna. As opposed to state-of-the-art CTS antenna designs, the proposed architecture achieves circular polarization using a single CTS array and without any polarization converter. The structure consists of long radiating slots/stubs fed by over-moded parallel-plate waveguides. More precisely, the transverse electromagnetic (TEM) mode and the first transverse electric (TE1) mode of the feeding waveguides are used to generate a circularly-polarized field. The array is analyzed using a spectral mode-matching method. First, the active reflection coefficient of the infinite array is derived in closed form. A windowing approach is then adopted to compute the radiation patterns of finite-size arrays. Numerical results obtained with this method are in excellent agreement with fullwave simulations, carried out with a commercial software. The performance of this class of CTS antennas has been investigated using the developed model. It is theoretically demonstrated that the proposed array can be designed to attain an axial-ratio (AR) lower than 3 dB over a 52.9% relative bandwidth at broadside. Furthermore, the active input reflection coefficient is lower than-10 dB over a 40.8% relative bandwidth when the array steers its main beam at θ0 = 45 •. This solution is an attractive candidate for next generation satellite communication terminals. Index Terms-Continuous transverse stub array, circular polarization, oversized parallel-plate waveguides.

“…A 16element X/Ku-band CTS FSA based on substrate integrated waveguides (SIWs) with a scanning-angle of 52.2° to -16.8° and peak gain of 18.1 dBi was proposed in [19]. In [20], SIW technology was also used, achieving a scanning range from −43° to 3° over the frequency range of 27 -36 GHz (28.5%) and a peak gain of 16.9 dBi. Still, all abovementioned CTS FSAs are based on PCB technologies.…”
