Design and characterization of a circular ring monopole antenna and its MIMO configuration for sub-6 GHz- sub-7 GHz and mm-wave 5G applications
(IOP Publishing Ltd, 2024) Sanaa Iriqat; Sibel Yenikaya; Mustafa Secmen; Iriqat, Sanaa; Yenikaya, Sibel; Secmen, Mustafa
In this paper a circular ring monopole antenna along with its MIMO configuration for sub-6 GHz sub-7 GHz and mm-wave 5G applications is presented. The single element spans a wide range of frequencies in the sub-6 GHz and mm-wave regions including a triple-band covering 1.9-6 GHz 23.3-33.5 GHz and a super-wide band starting from 37.5 GHz. A two-element MIMO antenna derived from the single element has been developed to operate in both frequency regions. It meets the - 10 dB criterion with a bandwidth of 4.8 GHz ( 3.2 to 7.3 GHz) in the sub-6 GHz/sub-7 GHz spectrum. Additionally the antenna exhibits a super-wide band in the mm-wave region starting at 30.4 GHz. The design covers key bands such as n78 LTE band 46 n96 39 GHz band 41 GHz band and more assigned for 5G sub-6 GHz sub-7 GHz and mm-wave applications. Improved isolation from 12 dB to 18.5 dB is achieved through a simple decoupling line structure between elements. The proposed MIMO antenna ( 75 x 56.4 x 1.52 mm3) exhibits a peak gain of 9.8 dBi high isolation ( 18.5 dB) low envelope correlation coefficient ( ECC < 0.016 ) high diversity gain ( DG > 9.995) and efficiency (< 97%).

Dual-Band 2 × 1 Monopole Antenna Array and Its MIMO Configuration for WiMAX Sub-6 GHz and Sub-7 GHz Applications
(Multidisciplinary Digital Publishing Institute (MDPI), 2024) Sanaa Iriqat; Sibel Yeni̇Kaya; Mustafa Seçmen; Iriqat, Sanaa; Yenikaya, Sibel; Secmen, Mustafa
This study introduces a cost-effective monopole antenna array and its MIMO configuration. The single element consists of a rectangular patch monopole featuring five circular slots at the center accompanied by two thin slots at the top offering a wide bandwidth (2–7.62 GHz) and a peak gain of 3.8 dBi. For gain improvement a 2 × 1 antenna array is demonstrated. This antenna array exhibits dual-band behavior, spans from 2 to 3.71 GHz and from 5.9 to 7.54 GHz, covers the 2.5 GHz band (2.3–2.7 GHz) a significant portion of the n78 band (3.3–3.71 GHz) and the n96 band (5.925–7.125 GHz), and is assigned to WiMAX sub-6 GHz and sub-7 GHz applications respectively. The antenna array achieves a peak gain of 6.47 dBi. Lastly a two-element MIMO configuration derived from the 2 × 1 array is designed. Implementing a defected ground structure (DGS) on the ground plane plays a crucial role in enhancing the isolation from 7 dB to 20 dB. The presented MIMO antenna covers the desired frequency bands of 2.5 GHz n78 and n96 with a peak gain of 7.5 dBi and high radiation efficiency (<99%) which qualifies it for WiMAX sub-6 GHz and sub-7 GHz applications. © 2024 Elsevier B.V.
