Bandwidth Upgrade in Printed Dipole Antennas Design for LTE Base Station

Abstract

In this research, the design of triple band printed dipole antenna is modified to enhance the antenna bandwidth and adjust its operating frequency range into the LTE allocated frequency band in Indonesia. The radiating elements of antenna are geometrically modified to adjust the bandwidth and resonant frequency range. The LTE frequency bands for Indonesia are taken as the reference frequencies. The design is initially assessed by using numerical simulation, then fabricated and empirically evaluated. The results shows that the proposed antenna can performs 81% in 900 MHz, 79% in 1,800 MHz, and 92% in 2,300 MHz which much better than previous reference design. The resonant frequency range of antenna also more compatible to allocated frequency bands.
