A wideband antenna with characteristics for low-frequency applications

This paper presents a wideband monopole antenna in a conical structure with a cylindrical element to promote the UHF band cover and indoor use. Predicted impedance bandwidth is 453.5MHz-1334MHz for VSWR<;2. Experimental results demonstrated that the proposed antenna can operate at the frequency band from 469MHz to 1387MHz which VSWR<;2. A resonance of the monopole along with the resonance provides the enough bandwidth to cover the DVB-T, LTE700, GSM850, and GSM900 bands. The project was made to be a lower cost and easy construction. The antenna shows peak gain of 3.3dBi. Also, simulation radiation patterns of the proposed antenna is presented. All simulations are carried out using EM commercial simulation, MWS-CST.
