This paper presents a 60 GHz connected slots linear-phased array feeding a high-gain semi-symmetric lens antenna. This design provides high gain, broadband, and beam-steering capabilities for gigabit rate access and backhaul communications. The connected slots antenna array (CSAA) is excited at 16× equidistant points which not only yields spatial power combining but also allows the progressive phase changes to steer the beam in ±45° in azimuth plane. To characterize the CSAA-fed lens antenna, four different power splitters are fabricated which steer the main beam in 0, 15, 30, and 45°. The lens is designed in a way to overcome the scan loss and get comparatively higher gain when beam is steered away from the broadside. The measured results show 25.4 dBi maximum gain with 3 dB gain bandwidth covering the full band 57–66 GHz whereas 3 dB beam-steering range is ±45° for all frequencies. Besides, the half power beamwidth is 6 and 10° in elevation (E-plane) and azimuth plane (H-plane), respectively.

“…The collimation property of dielectric focal points over a multi-band set of little-size fixed radio wires was discussed. They have likewise planned a Microstrip cluster radio wire with its printed feed network on a solid substrate for the upgrade with a dielectric focal point and acquired further increase, [13] which means a compelling bigger radio wire. Actual conservativeness could now be accomplished by diminishing the number of components in consonance with the collimation given by the focal point, [8], [9].…”

Examining and evaluating the improved microstrip patch antenna to enhance the performance by the initial objectives are the main contribution of this paper. To achieve multiband operation, the patch's shape is first adjusted later microstrip patch with the slot presented. With the help of the Ansoft HFSS antenna simulator, functional analysis has been shown to examine the impact on antenna resonant frequency. A probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is developed in this work via the HFSS tool for wireless applications operating between 2 to 5GHz. To achieve multiband operation, the structure of the patch is varied. The impacts on antenna resonant frequency are examined through numerical simulations. The length, as well as the width of a traditional patch antenna, is initially computed, and further, an appropriate patch dimension of 28.3mm x 36.9mm has been determined. For multiband operation over the frequency ranging between 2 and 5GHz wireless applications, a probe-driven microstrip patch antenna imprinted on FR4 epoxy substrate with 1.6mm thickness and a dielectric constant of 4.4 is built via the HFSS tool. The proposed architecture of a traditional microstrip patch antenna is imprinted on an FR4 epoxy substrate with a 1.6mm thickness and a 4.4 dielectric constant. The proposed antenna design is illustrated for the 3D structure of the Mutual Coupling Steered Array-Lens Antenna System (MPA) with an improved patch. To achieve multiband operation, two slots are inserted on the edges of the patch, and both the slots are 2mm wide, as well as the depth of the slots is modified to see how it corresponds to the resonant frequency. This work is mainly concentrated on (i) Examining as well as evaluating the improved microstrip patch antenna to enhance its performance, (ii) Examining, evaluating, as well as assessing the performance of an improved split ring resonator metamaterial, and (iii) Exploring, analyzing, as well as evaluating the performance of dielectric lens base patch array antennas and (iv) Developing as well as analyzing the transmission line phase shifter. The groundwork for developing this work is being carried out, and a comparative study is made on (i) techniques for improving the antenna's performance through the application of a modified patch antenna, a Modified split ring resonator, a Dielectric lens structure, and Transmission line phase shifter.
