The goal of this paper is to propose a new antenna array architecture, that aims to solve the most known limitations of phased antenna arrays, resulting a good candidate for next 5G mobile handsets. The architecture consists of five Quasi-Yagi antennas printed on the short edge of a Roger RO3003 substrate, pointing different directions, and a switch to feed each antenna and steer the beam. Simulations prove that the antenna array can cover the angle of over 180 • with high gain over the frequency range from 26 to 40 GHz. Alternative designs to make the structure more compact further demonstrate the validity of the concept. The optimized corner array of four elements is fabricated and passive and active measurements are performed with the MVG Starlab 50 GHz. The results of the passive measurements are in accordance with the simulations and show that the proposed Quasi-Yagi antenna array has large coverage over the whole bandwidth and peak gain of 8 dBi at 28 and 38 GHz. The active measurements of the array connected to the FEM and integrated in the phone-case further confirm the radiation properties of the switchable antenna array at 28 GHz in a quasi-real scenario.

“…Comparatively, the antenna designs that most closely match the performance characteristics of our high-gain lens antenna are array antennas. Nonetheless, a notable benefit of our lens antenna design, as highlighted in references [34][35][36][37][38][39][40], is its capacity to address and overcome several significant challenges commonly associated with array antennas, as compared in Table 1.…”

“…Specifically, lens antennas avoid the necessity for extensive, expensive millimeterwave substrates and intricate [34], costly manufacturing processes. Moreover, they eliminate the need for complex feed network designs [34][35][36][37][38][39][40], which simplifies the overall antenna implementation and significantly reduces associated costs. This simplification not only streamlines the development process but also enhances the economic viability of deploying advanced lens antennas in millimeter-wave applications.…”

This study introduces a groundbreaking antenna system, the directive Metasurface Half-Maxwell Fish-Eye (MHMF) lens antenna, tailored specifically for Internet-of-Things (IoT) networks. Designed to operate at 60 GHz, this antenna ingeniously integrates a dipole antenna within a parallel-plate waveguide to illuminate a Half-Maxwell Fish-Eye (HMFE) lens. The HMFE lens serves as a focal point, enabling a crucial high gain for IoT operations. The integration of metasurface structures facilitates the attainment of the gradient refractive index essential for the lens surface. By employing commercial Ansys HFSS software, extensive numerical simulations were conducted to meticulously refine the design, focusing particularly on optimizing the dimensions of unit cells, notably the modified H-shaped cells within the parallel waveguides housing the beam launchers. A functional prototype of the antenna was constructed using a standard PCB manufacturing process. Rigorous testing in an anechoic chamber confirmed the functionality of these manufactured devices, with the experimental results closely aligning with the simulated findings. “Far-field measurements have further confirmed the effectiveness of the antenna, establishing it as a high-gain antenna solution suitable for IoT applications. Specifically, it operates effectively within the 60 GHz range of the electromagnetic spectrum, which is crucial for ensuring reliable communication in IoT devices.” The directive HMFE lens antenna represents a significant advancement in enhancing IoT connectivity and capabilities. Leveraging innovative design concepts and metasurface technology, it heralds a new era of adaptable and efficient IoT systems.

“…The Vivaldi element has overall dimensions of 3.31 mm × 3.61 mm, and it is implemented on Rogers RO3006 substrate with a dielectric permittivity of 6.15 and thickness of 0.64 mm. The Vivaldi antenna is fed by a microstrip line ended with a radial stub [23], but other feeding methods like SIW [24] can be employed. The coupled metal strip layers are etched on CuClad 217 substrate of r = 2.17 and thickness of 0.254 mm to facilitate the fabrication.…”

In this paper, a novel technique is introduced to reduce the handset metal-frame blockage to the main beam of a millimeter-wave (mm-wave) end-fire antenna array. The metalframe blockage to mm-wave antennas with different polarizations is investigated first. It is found that the blockage is more severe for horizontal polarization than for vertical polarization. The effect of the metal bezel on a mm-wave array with horizontal polarization can significantly be decreased if two tilted layers of coupled metal strips are placed at the borders of the frame. Furthermore, these metal strips are shown not to disturb mmwave antennas with vertical polarization. Different detailed design considerations are studied. To further demonstrate the idea, a 5G Vivaldi array (with horizontal polarization) is designed and integrated with a metal frame. The frame functions as a lowfrequency antenna, operating in two frequency bands of 865-990 MHz and 1358-2786 MHz. The millimeter-wave array with four elements operates at the frequency band 24.25-27.5 GHz and can scan ±60 degrees in end-fire direction, with a realized gain higher than 7 dBi in most of the frequency range.Index Terms-5G mobile communication, antenna array, millimeter wave integrated circuit, Vivaldi antennas.
