Abstract

A novel compact broadband monopole antenna inspired by a Vivaldi antenna is presented. In order to get a compact solution, the profile of a slot Vivaldi antenna has been modified and a wideband antenna covering LTE700, GSM850, GSM900, DCS1800, PCS1900, WCDMA2100, Bluetooth, WiMAX2350, WLAN2400, and LTE2600 standards has been obtained, with a size reduction length of 30% over conventional λ/4 monopole antennas. In contrast to traditional designs using Vivaldi antennas, a compact design with omnidirectional radiation pattern is proposed. Simulated and measured results are provided, which verify the broadband behavior of the antenna. In addition, the proposed design is perpendicularly mounted to a ground plane, being then suitable for mobile communications in vehicular applications.
