The dielectric resonator antenna is designed to operate at higher-order <inline-formula> <math display="inline"> <semantics> <mrow> <mi>T</mi> <msubsup> <mi>E</mi> <mrow> <mi>&#948;</mi> <mn>15</mn> </mrow> <mi>x</mi> </msubsup> </mrow> </semantics> </math> </inline-formula> mode to achieve high antenna gain, while a hollow cylinder at the center of the DRA is introduced to improve bandwidth by reducing the quality factor. The DRA is excited by a <inline-formula> <math display="inline"> <semantics> <mrow> <mn>50</mn> <mo>&nbsp;</mo> <mi mathvariant="sans-serif">&#937;</mi> </mrow> </semantics> </math> </inline-formula> microstrip line with a narrow aperture slot. The reflection coefficient, antenna gain, and radiation pattern of the proposed DRAs are analyzed using the commercially available full-wave electromagnetic simulation tool CST Microwave Studio (CST MWS). In order to verify the simulation results, the proposed antenna structures were fabricated and experimentally validated. Measured results of the fabricated prototypes show a 10-dB return loss impedance bandwidth of 10.7% (14.3&#8722;15.9GHz) and 16.1% (14.1&#8722;16.5 GHz) for DRA1 and DRA2, respectively, at the operating frequency of 15 GHz. The results show that the designed antenna structure can be used in the Internet of things (IoT) for device-to-device (D2D) communication in 5G systems. 2020-11-05T03:58:15Z 2020-11-05T03:58:15Z 2020-01 Article Sensors, vol.20(3), 2020, 12 pages 1424-8220 (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/68620 https://doi.org/10.3390/s20030675 en MDPI AG
