The paper proposes a 5G millimeter-wave antenna with circular molded slots to increase the performance of the antenna. The antenna resonates at 24.8 GHz and 33.2 GHz, achieving S11 magnitudes of 18.60 dB and 23.2 dB, respectively. The antenna that has been proposed is designed by imposing circular slots with a defective ground structure that produces dual bands over the frequency range of 21.59 GHz to 25.72 GHz and 29.31 GHz to 35 GHz, respectively. We print the antenna on a RT Duroid dielectric material, measuring 44 × 36 mm2, and use the EM simulation tool CST Studio to perform numerical simulations. The antenna achieved peak gains of 4.63 to 5.11 dBi at the corresponding frequencies. The antenna’s simulation results show that the proposed antenna is suitable for millimeter-wave applications.

摘要

The paper proposes a 5G millimeter-wave antenna with circular molded slots to increase the performance of the antenna. The antenna resonates at 24.8 GHz and 33.2 GHz, achieving S11 magnitudes of 18.60 dB and 23.2 dB, respectively. The antenna that has been proposed is designed by imposing circular slots with a defective ground structure that produces dual bands over the frequency range of 21.59 GHz to 25.72 GHz and 29.31 GHz to 35 GHz, respectively. We print the antenna on a RT Duroid dielectric material, measuring 44 × 36 mm2, and use the EM simulation tool CST Studio to perform numerical simulations. The antenna achieved peak gains of 4.63 to 5.11 dBi at the corresponding frequencies. The antenna’s simulation results show that the proposed antenna is suitable for millimeter-wave applications.
