A High-Gain Quasi-Fractal Antenna with Wide Range Operation for 5G Applications over V-Band Spectrum

چکیده مقاله

In this paper, a vertical cascade of T-shaped fractal-like antenna is presented for operating at V-band. The fractal-like antenna is shown to provide wideband performance. The radiator consists of interconnected series of elliptical structures of different sizes that were constructed on Roger RT/duroid 5880 substrate. The proposed antenna design was verified using HFSS and CST electromagnetic solvers. The overall dimension of the antenna is 16×18×0.79 mm3. The antenna is shown to provide an average gain exceeding 6.5 dBi across 59 GHz to 68 GHz. The simple geometrical configuration of the antenna and its radiation characteristics makes it a potential candidate for 5G applications operating in V-band.
