Abstract

In this study, a compact ultra-wide band microstrip antenna loaded with C-shaped parasitic elements, for Digital Video Broadcasting – Terrestrial (DVB-T) and LTE 450 / 700 signal reception, is presented. The proposed antenna is named “HI Monopole”, and its geometry has been designed to be simple and intuitive, lightweight, compact, possessing a low fabrication cost as well as an easy installation process inside electronic gadgets. The HI Monopole operates with ultra-wide bandwidth characteristics for operation within Digital Video Broadcasting – Terrestrial (DVB-T) standard, 470–890 MHz, that has been accomplished by: inserting an indent in its ground plane, adjusting the dimension of the feeding line, and adding two C-shaped parasite elements onto the region posterior to the antenna’s main irradiating element. It was verified through electromagnetic measuring that this device is capable of covering the 429-1022 MHz range, thus having 593 MHz of bandwidth. The superior and inferior cutoff frequencies have been chosen as the values in –10 dB of the device’s return loss. Therefore, the proposed antenna can be utilized in DTV and LTE signal reception through broadcasting in any country, independently of its adopted standard.
