Abstract
In this paper, antipodal Vivaldi antenna is designed for 5th generation (5G) mobile communication and Ku-band applications. The proposed designed has three layers. The upper layer consists of eight-element array of split-shaped leaf structures, which is fed by a 1-to-8 power divider network. Middle layer is a substrate made of Rogers 5880. The bottom layer consists of truncated ground and shorter mirror-image split leaf structures. The overall size of the designed antenna is confined significantly to 33.31 × 54.96 × 0.787 (volume in mm3), which is equivalent to 2λo× 3.3λo× 0.05λo (λo is free-space wavelength at 18 GHz). Proposed eight elements antenna is multi-band in nature covering Ku-bands (14.44–20.98 GHz), two millimeter wave (mmW) bands i.e., 24.34–29 GHz and 33–40 GHz, which are candidate frequency bands for 5G communications. The Ku-Band is suitable for radar applications. Proposed eight elements antenna is very efficient and has stable gain for 5G mobile communication and Ku-band applications. The simulation results are experimentally validated by testing the fabricated prototypes of the proposed design.

Accepted: 16 December 2020The cellular communication system is the backbone of wireless communication and is widely used for transmission of data in the form of voices, images, and videos between users
Fifth generation (5G) is preferred over 4G owing to the availability of wide bandwidth which enhances network performance
This section covers the design and optimization of the single element antenna followed by detail analysis of multi-element array designs in order to obtain the required performance matrices for the targeted 5th generation (5G) application
Summary
The cellular communication system is the backbone of wireless communication and is widely used for transmission of data in the form of voices, images, and videos between users. By the introduction of high speed packet access (HSPA) and long term evolution (LTE) advanced, third generation (3G) is evolved to fourth generation (4G). High volume data can be transferred in the form of tens of megabits per second (Mbps) to thousands of users simultaneously [8]. It reduces power consumption and provides improved spectral efficiency and enhanced coverage [9]. The usage of millimeter wave (mm wave) will improve the quality of the wireless communication system [10,11,12]
