A Gain Embedded V-Integrated Rectangular Slotted Triangular Edged (EVI-STE) Design for Wireless 5G Mobile Applications

This paper presents a new nonlinear ground fractal antenna design, named as, Embedded V-Integrated Rectangular Slotted Triangle Edged (EVI-STE) antenna for wireless communications. In this proposed design slots of different shapes have been loaded to optimize the characteristics of an antenna such as return loss, impedance matching, gain and radiation pattern. The proposed antenna is employed with defected ground to reduce the return loss and the antenna is fed by microstrip line. The peak gain is 3dB with VSWR < 2 which shows that there is good impedance matching throughout the circuit. Antennas are designed on low-cost FR-4 glass epoxy substrate with relative permittivity of 4.4 and overall dimension 21×25mm 2 Comparison among antennas have been made and found that the proposed antenna exhibit better results in the fourth iteration in terms of bandwidth, impedance matching, number of frequency bands, and gain. The antenna is designed and simulated using HFSS and obtained good output response at 3.8, 5.6, 8.2 GHz which makes it suitable for 5G applications.
