“…High radiation performance with low side lobe levels are achieved but in narrow bandwidth and without modularity. The authors in [18] introduce an array of 4 hollow SIW horn antennas with a high efficiency, but the modularity of the array design is limited. The work in [15] proposes a modular design of vertically stacked H-plane SIW horns.…”

This paper presents a vertically stacked SIW antenna array that enables different array configurations with the minimum number of SIW layers. This achievement lies in the modular feature offered by the proposed design. Specifically, 4 distinct array configurations can be produced with only 3 different design of SIW layers. Depending on the number of SIW layers employed in the stacked antenna, the directivity in the E-plane is modified. To obtain an equal and in-phase power distribution among the array elements, H-and E-plane corporate feeding networks are efficiently implemented in each array configuration. Array configurations of 1, 2, 4 and 8 radiating layers are offered by the proposed modular array, where each radiating layer is formed by 8 H-plane horn antennas. The simulated directivity for the array configurations ranges from 15.8 dBi to 23.8 dBi and the main beam direction remains fixed along the operating frequency range. The array design has been manufactured and agreement between simulated and measured results are observed. The measured impedance bandwidth in all the array configurations is from 35 GHz to 41 GHz (15.79% bandwidth) with a reduction in the E-plane beamwidth as the number of radiating layers increases.

“…SIW technology is often adopted to ease fabrication and integration of horn antennas operating at mm-wave frequencies [87][88][89]. A relevant example of that can be found in [88], where a 1 × 4 array of hollow SIW (HSIW) H-plane horn antennas are realized using conventional, inexpensive though lossy, FR4 laminates. Under such assumption, HSIW technology provides an effective means for avoiding/reducing dielectric losses.…”

With the introduction of 5G communication systems operating in the mm-wave frequency range, new opportunities in terms of multimedia services and applications will become available. For this to happen, several technical challenges from an antenna standpoint need to be addressed. The achievements of high-gain characteristics and agile beamforming with wide-scan capabilities are the main targets of the ongoing research on mm-wave antenna arrays. In this paper, an up-to-date overview of antenna array technology for wireless communications at mm-wave frequencies is given. Particular focus is put on the review of the state-of-the art and most advanced antenna array concepts for point-to-point and point-to-multipoint radio links at said frequencies. Various figures of merit are assessed for a comprehensive analysis and bench marking of the technical solutions investigated in the presented survey.

“…This kind of transmission line is fabricated using low-cost FR4 PCB at the MMW band and combines the advantages of metallic waveguide and SIW. Filters, phase shifters, and antennas based on ESIW technologies have been reported [20][21][22][23][24][25][26]. Circularly polarized (CP) antennas can effectively reduce multipath interference and exhibit better channel performance compared to that of linearly polarized antennas.…”

A high‐gain, low‐cost empty substrate integrated waveguide (ESIW)‐fed circularly polarized (CP) antenna array is demonstrated for millimetre‐wave 5G applications in this letter. The ESIW is formed by metallized FR4 printed circuit boards. By stacking the metallic aluminium z‐shaped radiating slots atop the ESIW feeding network, CP radiation is achieved. The proposed 1 × 8 antenna array offers a high measured gain of 17.8 dBic and high measured radiation efficiency of 89.1%. The measured impedance bandwidth for |S11| ≤ −10 dB and measured axial ratio (AR) bandwidth for AR ≤ 3 of the proposed 1 × 8 array are 11.4% (36.5–40.9 GHz) and 7.8% (37–40 GHz), respectively.
