“…Research on mm-wave antenna design in many applications such as 5G wireless communication [7], sensing, and security has become of interest. Many researchers worldwide have launched a series of studies about mm-wave micro-strip antennas [8,9], but the disadvantages of weak gain and efficiency remain constraints. 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 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.

“…Signal integrity, selectivity, and energy transfer are all improved by a high-quality factor. The temperature stability of the active component is maintained by a near-zero temperature coefficient of resonant frequency [8][9][10][11][12]. However, despite their excellent dielectric properties, microwave dielectric ceramics have some drawbacks, including high brittleness, high sintering temperatures, complicated processing, and expensive cost, which represent crucial limitations on their uses [13,14].…”
