“…7 shows the geometry and dimension parameters of the designed dipole antenna. The designed dipole antenna was constructed using a 10-layer FR4 stack substrate, which is widely used in commercial millimeter-wave antenna-in-package solutions since the fabrication cost was lowered by the rapid development of 5G technology [24]- [27]. To be compatible with this printed circuit board, two arms of the dipole antenna were connected to different layers, with one connected to the 5th, signalline layer, and the other to the 6th, ground layer, as shown in Fig.…”

This paper describes a millimeter-wave thin lens that exhibits different beam-shaping characteristics depending on the polarization of the incident waves. The proposed unit cell topologies, which use multiple rectangular patches and rectangular-slotted grids, enable thinner (= 0.05λ 0) and smaller (= 0.168λ 0) features than in previous polarization-dependent lenses. An appropriate set of the proposed unit cells is shown to cover a tunable phase range of 180 • with respect to one polarized wave but have an almost-zero tunable range of phase shifts with respect to another polarized wave. Thus, using this unit cell set for x-polarized incident waves, the proposed lens operates as a convex lens, whereas for ypolarized incident waves, the lens operates as a frequency selective surface. This confirms that gain variations of 13 dB or more can be differentiated according to the polarization of the incident waves on the lens, supporting polarization-dependent beam-shaping capability as a function of the polarization of incident waves.

“…A 4 × 4 array configuration is selected for beam steering capability, which is an essential functionality for a wireless backhaul system requiring a slight beam adjustment of a few degrees in deployment scenarios. The designed patch antenna array is fabricated using a 10-layer FR4 stacked substrate, which is widely used in commercial millimeter wave antenna-in-package solutions because of the rapid development of 5G technology with a low manufacturing cost [17,18,19,20]. The thickness of the antenna substrate is 0.762 mm, and the dielectric constant and loss tangent are 4.2 and 0.002, respectively.…”

This paper proposes a novel design approach for a thin lens with the aim of overcoming fineness limits in the commercial millimeter wave printed circuit board (PCB) manufacturing process. The PCB manufacturing process typically does not allow the fabrication of metallic patterns with a gap and width of less than 100 μm. This hampers expanding thin lens technology to 5G commercial applications, especially when such technology is considered for 60 GHz or higher frequency, which requires a finer gap and width of metallic traces. This paper proposes that problematic process conditions can be mitigated when a lens is designed by establishing single-polarized lumped element models where larger capacitance and inductance values can be obtained for the same patch and grid unit cells. While the proposed design technique is more advantageous at higher target frequencies, a 60 GHz application and a wireless backhaul system is selected because of a limited range of frequencies that can be measured by an available vector network analyzer. The required gap or width of metallic traces can be widened significantly by using the proposed single-polarized unit cells to acquire the same in-plane capacitance or inductance. This enables the lens operating at higher-frequency under the process limits in fabricable fine traces. Finally, the effectiveness of the simulated design procedure is demonstrated by fabricating a 60 GHz thin lens that can achieve a gain enhancement of 16 dB for a 4 × 4 patch antenna array with a gain of 16.5 dBi.

This article proposes modified fractal antennae for wideband applications. The proposed antennas have a resonance frequency range of 10–40 GHz. Modified fractal antennae are designed and fabricated with a height of 1.6 mm, substrate width, and length of 35 mm2. The simulated result shows that the peak gain is increased by 6–8 dBi for the proposed designs DGS 1 and DGS 2 concerning fractal antennae FA 1 FA 2. Based on the proposed designs, the designed DGS 1 and DGS 2 antennae radiate power with a peak directivity of 8.58–13.3 in dBi concerning fractal antennae FA 1 FA 2. The proposed antennas with expected 6G and 5G NR bands have more radiation concerning resonate frequencies such as 14, 30, and 37 GHz, and 14, 17.1, 19.5, 30, 33.2, and 36.92 GHz in the 10–40 GHz range with Phi = 0°, Phi = 90°, and Theta = 90° concerning designs DGS 1 and DGS 2. At frequencies in the mm‐wave range, the antenna has more fluctuations, and current distribution is concentrated on fractal slots, in which antennas have more radiation. Proposed antennae have pencil beam properties required for advanced 5G mm‐wave communication. A more radiating antenna has a maximum return loss of 27 and 30 dB for designs DGS 1 and DGS 2, respectively. Moreover, the bandwidths covered in the 5G NR and expected 6G frequency ranges are 13.5–16.8 GHz, 27–38.1 GHz, and 12.63–14.68 GHz, 15.3–40 GHz, concerning designs DGS 1 and DGS 2. The proposed antennae have multiband, which cover more applications in the n257, n258, n259, n260, and n261 5G NR bands and expected 6G bands with the ground‐based radio navigation applications, and so forth. The proposed fabricated antennas also cover 5G and expected 6G applications with good matching. The proposed antennae have been simulated using CST, and the results of the fabricated antenna have been validated using the vector network analyzer, spectrum analyzer, and power sensor.
