This research presents a flower-shaped design of a multi-input multi-output (MIMO) antenna with dual wide operating bands in the millimeter-wave (MMW) region proposed for 5G applications. The antenna system consists of a quad-port antenna array placed with a 90-degree shift; it was etched on a low-cost FR-4 dielectric substrate with a full size of 22221 mm3. The objective of this work it to enhance the bandwidth of the proposed MIMO antenna as well as to increase the antenna gain. To increase the gain, we used multiple single antennas and to enhance the bandwidth we added some slots to the suggested antennas. The array antennas are designed to provide dual-band operation at the frequencies of 29 GHz (n257) and 39 GHz (n259). The results are simulated using HFSS, acceptable gain reaches 3.04 dB and 8.11 dB in the first and second bands, respectively, while the impedance bandwidth achieved by the design is about 1600 MHz (28.9-30.5 GHz) at 29.8 GHz and about 2330 MHz (38.43-40.76 GHz) at 39.6 GHz with a reflection coefficient S11 of about – 16.20 dB and – 19.27 dB, respectively. The proposed antenna can be a desire choice for 5G applications because of its low cost, small size, high performance in terms of bandwidth and gain. |
