A compact dual-band Dolly-shaped antenna with parasitic elements for automotive radar and 5G applications. En Heliyon (Vol. 7, Número 4, p. e06793). https://doi.org/10.1016/j.heliyon.2021.e067932405-8440 (Print) 2405-8440http://repositoriobibliotecas.uv.cl/handle/uvscl/3108In this paper, a compact dual-band Dolly-shaped antenna (DBDSA), resonating at 23.52 GHz and 28.39 GHz, is proposed for automotive radar, 5G, and Industrial, Scientific, and Medical (ISM) applications. The antenna is designed on a 7 � 7 � 1.28 mm(3) which is 0.541?(0)�0.541?(0)�0.099?(0) in electric size, where ?(0) represents the free space wavelength at 23.16 GHz. Rogers RO3010 substrate with a dielectric constant of 10.2 and a loss tangent is about 0.0022 has been used. Two F-shaped parasitic elements and a rectangular slot have been used to achieve the desired electromagnetic antenna performances. After modeling and optimizing the proposed antenna configuration through High-Frequency Structure Simulator (HFSS) software, its prototype was manufactured and measured to validate the simulated results. The DBDSA achieves an overall radiation efficiency of 80% within the two operating frequency bands. The radar band exhibits a stable gain of 5.51 dBi, while the 5G band has a gain of 4.55 dBi. Furthermore, the experimental results show that the |S(11)|?-10 dB bandwidths are 1.16 GHz (23.16 GHz-24.32 GHz) in the lower band and 634 MHz (28.078 GHz-28.712 GHz), respectively. A good agreement is found between the simulated and measured results.en-US5G AUTOMOTIVE RADARDUAL-BAND ANTENNAISM APPLICATIONSPARASITIC ELEMENTSArticulo
