“…Moreover, aperture radiating elements can be easily implemented together with waveguide or SIW feeding networks. A slotted linear array was entirely manufactured by the authors in a single‐layer substrate using SIW technology, achieving good side‐lobe level (SLL) and impedance matching . Compact structures are attainable with linear arrays, reducing manufacturing costs and avoiding grating lobes issues.…”

In this article, a linearly polarized 2 × 2 patch array uniformly fed by a corporate substrate integrated waveguide network for Ku band is presented. Undesired main beam steering is avoided by means of a fully corporate feeding network, although grating lobes may appear due to greater separation between radiating elements. Moreover, a reduced patch separation to avoid grating lobe appearance leads to an antenna matching coefficient degradation due to the proximity of antenna discontinuities. In consequence, a tradeoff approach has been developed, achieving a measured 4.1% matching bandwidth and a measured gain of 13.27 dBi, which corresponds to an 86% radiation efficiency. Good agreement between simulated and measured results is observed in all cases. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:587–593, 2016

“…To overcome these shortcomings, many substrate integrated waveguide (SIW) cavitybacked CP slot antennas have been proposed. The following three main radiating configurations of CP SIW cavity-backed slot antennas have been proposed in the literature: compound slots [5][6][7][8][9], annular, triangular or split ring slot [10][11][12][13] and patches, loop or cavity that cover the slots [14][15][16][17][18][19].…”

Abstract-A circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed antenna based on dual concentric, orthogonal slot split ring resonators is proposed and experimentally studied. The circularly polarized wave is generated by two split ring-slots etched in the upper metal layer of the SIW cavity resonator. These two slots are excited by a coaxial probe located in the gap of the external slot split ring to radiate the right-handed circularly polarized (RHCP) wave. By rotating the dual split slot ring resonators and the probe by 45 degrees relative to the backed cavity, a better match characteristic and a slightly higher radiation gain are obtained. Because of the concentricity of radiant split ring slots, the beamwidth of the circular polarization is obviously increased. From the experimental results, the impedance bandwidth was 10.8% for the reflection coefficient less than −10 dB, the axial ratio (AR) bandwidth was 1.54% for the AR less than 3 dB, and the RHCP gain was 4.44 dBic. Moreover, the 3-dB axial ratio beamwidth at the centre frequency of 10.40 GHz has been extended to 142 • in the angular range from −78 • to +64 • .

“…Slots are easily integrated in SIW in the shape of linear arrays [2]. The most straightforward feeding topology to use in these arrays is progressive wave feeding, though the overall bandwidth is reduced due to main-beam steering as frequency sweeps.…”

A 4 x 4 linearly-polarized stacked-patch array with a fully corporate feeding network for Ku-band is presented in its work. Antenna replication in larger arrays is straightforward with this corporate approach, which in addition prevents unintended main beam steering. The feeding structure is divided in two levels, where the first power distribution is made in Substrate Integrated Waveguide and the second in microstrip technology. This procedure takes advantage of the strengths of each technology, combining waveguide low losses with microstrip versatility. A 18.4-dBi gain is attained in simulation with matching better than -14 dB in the entire bandwidth.
