Design and implementation of combined array antenna for point to point 5 g mm-wave communication and wireless applications

Abstract

This study proposes a proposed combined DGS array antenna for multiband applications. Advanced quantum communication relies on large array antennas, pivotal for transmitting and receiving quantum information. This study introduces a combined array antenna for Multiband quantum 5G, with resonance frequency spanning 24–40 GHz, featuring 20 elements, combining circular central feeding. The proposed antenna has a 1.6 mm height with a roger substrate with 20 mm length and width, respectively, and the proposed antenna resonates with Multiband beam coverage with gain increased as 7.8 and 7.6 dBi at resonate frequencies of 28.82 and 35.44 GHz, respectively. The proposed antenna radiated power in a given direction with a directivity of 6.72 dB and 8.1 dB, respectively. The proposed antennae with 5G NR bands have more radiation concerning resonate frequencies in the 24–40 GHz range with Φ = 0⁰, Φ = 90⁰, and θ = 90⁰, respectively. Furthermore, its 5G NR bands application covers bandwidths of 2.75 and 2.03 GHz with good return losses of 49.38 and 60.85 dB concerning resonate frequency as 28.82 and 35.44 GHz, respectively, and cover 5 G quantum mm-wave applications and NR 5G bands as n257, n258, n260, and ground-based navigation in range of 27.85 to 34.62 GHz and 30.6 to 36.65 GHz have resonating notches as 24.39, 29, 29.7, 32.4, 36.25, and 39.07 GHz with return losses of 18.5, 26.3, 22.3, 21.6, 21.2, and 15.1 respectively and have received power measured as -50 dBm, respectively and has been implemented and validated using CST, VNA, Spectrum Analyzer, and Power Sensor with an Absorber.
