The goal of this paper is to design a dual-band antenna for the integration of LTE-R 700MHz band along with 5G (3.5 GHz) band applications for future advanced railway communication. A design study of the dual-band antenna is proposed and discussed in detail. An ellipse-shaped ring patch is designed for the LTR-R 700-MHz band, and the 5G (3.5 GHz) band is added by keeping the circular patch in proximity to the feed line of the antenna to make it a stacked antenna configuration. Circular patches with varying dimensions are used to increase the bandwidth at 3.5-GHz band. The antenna has a size of 180mm×60mm and is fabricated on an FR4 substrate with dielectric constant 4.4 (tan δ = 0.025). The observed bandwidth is approximately 100 MHz and 500 MHz for each frequency band respectively.
