“…It also stands out [ 24 ] for the G and BW that it provides considering its small size, although its performance is outmatched by the proposed antennas. The antenna designs corresponding to ε r values, which are slightly higher than 3 and lower than 3.6, [ 40 , 47 , 48 , 49 , 50 ], provide results of G lower than 14 dBi and with BW similar to that shown by the basic antenna of the present work [ 47 , 48 , 50 ], and in all cases lower than that provided by the antennas with metasurfaces proposed in this work. It can be highlighted [ 48 ] with G = 13 dBi, which could be compared with the basic array proposed here, although [ 48 ] with lower BW and G, and taking up more area despite using a higher ε r .…”

Three metasurfaces (MTS) are designed to be combined with a series end-fed 1 × 10 array antenna with a modified Dolph-Chebyshev distribution for imaging applications in the millimeter frequency range, 24.05–24.25 GHz. A reduction in secondary lobes and an increase in FTBR can be achieved while preserving gain, radiation efficiency, SLL and size using an MTS–array combination. Moreover, as a result of each single-layer MTS–array combination, operation bandwidth is widened, with gain and radiation efficiency enhancement. The overall devices’ size is 86.8 × 12 × 0.762 mm3. The envisioned application is collision avoidance in aid to visually impaired people at a medium-long distance.

Tank level measurement is an important research area in radar technology. Level measurement using radar technology is a safe solution even under extreme process conditions, such as high pressure, temperature, and vapors. Special antennas are required to meet electromagnetic requirements such as high gain, low sidelobe level, and high bandwidth. Another requirement is a small size and good manufacturability of the antenna. One promising solution is the use of microstrip antennas for tank-level measurements. This paper presents a special microstrip antenna, that meets the main requirements in addition to a circular antenna layout, which fills optimally the tank hatch. To do this, we created a special antenna layout with a suitable feeding network and added an optimized ring around the antenna system, which significantly reduces the sidelobe level. The center frequency of the antenna is 25 GHz with a 1 GHz bandwidth.

“…Therefore, there's a requirement for designing array antennas [10][11][12][13][14][15] as one of the solutions to accomplish higher values of efficiency and gain to overcome the path loss resulting from atmospheric conditions. The use of array antennas aims to increase the directivity [16], the gain [17][18][19], and enhance other characteristics that would be difficult with simple antennas. Micro strip patch antennas (MPAs) have been incorporated into a variety of applications, including radio-frequency identification (RFID) [20], and multiple -input multipleoutput (MIMO) systems [21], they have been the subject of numerous studies because they are considered core devices for wireless technology.…”

The goal of this work is to create a new patch antenna array with a standard gain, broadband, unidirectional radiation pattern, and high efficiency, making it a viable contender for millimeter-wave wireless applications. This study begins with a simple single-patch antenna that has four key components to provide effective matching and a wide impedance bandwidth: elliptical lateral edges, vertical stubs, slots expressed in concavity, and notches. The ground plane was defect-free, and the patch was printed on a Rogers RT5880 substrate. The performance of the proposed antenna can be improved using array topologies of 1×2 and 2×2 patches, for which a corporate feed network was built for excitation. The suggested 2×2 array antenna with a compact size of 18x16.1 mm2 achieved a gain of 13.8 dB, 92% efficiency, a return loss of-34.8 dB, and an ultra-wide bandwidth of 12.2 GHz (ranging from 39.9 to 52.1GHz) at a resonant frequency of 43.2. It’s a novel compact 2×2 array antenna appropriate for miniature devices is suggested using CST studio software, which gathers all qualities together, including high-gain, radiation efficiency, and ultra-wideband. The planned antenna operating frequency range runs from 27 to 58 GHz, which encompasses multiple frequency bands, such as V, Q, and Ka.
