- Abstract
A compact with a high gain antipodal Vivaldi antenna (AVA) is implemented for 5G applications. The proposed AVA dimensions are 24 mm × 50 mm × 1 mm. The 'V' metamaterial exhibits negative relative permittivity property and hence it is epsilon negative metamaterial (ENG). These ENG unit cells are arranged in between two flares of AVA to transfer most of the energy in the end-fire direction. The antenna gain varies between 10.9 and 13.82 dBi in the entire frequency range of 24–30 GHz which makes it suitable for 5G communication applications. Also, the proposed antenna covers 24.25–29.50 GHz 5G frequency spectrum band. Next, the simulated results and the measured results match each other. Because of its wide bandwidth, enhanced gain, and compactness, the proposed antenna is preferable for employing it in the 5G communication devices.
