Performance Analysis of Dual-Arm Printed Monopole Antenna for LTE1800/2600

Abstract

Dual-arm printed monopole antenna covering 1.8GHz and 2.6GHz bands for LTE applications is presented. The antenna consists of two parallel monopoles fed by a microstrip line. The ground plane is of length 40 mm and width 50 mm. The 50Ω microstrip feed line and the dual-arm monopole are printed on a dielectric substrate at the opposite side of the ground plane. The dielectric substrate is made of FR4 material which has dielectric constant of ɛr = 4.5 and thickness of 0.8mm. The proposed antenna provides a good return loss, omni-directional radiation patterns, and good directivity. The proposed antenna is simulated using the 3-D electromagnetic solver of CST®.
