Abstract :
This work presents a novel broadband monopole antenna for digital video broadcasting-terrestrial (DVB-T) application. The proposed antenna consists of a grating patch and a concave rectangular ground plane with defected ground plane. The added part in the ground plane is used to enable the antenna height reduction for fixed ranges of operating frequency. The proposed antenna can operate from 470 MHz to 870 MHz frequency range corresponding to 60 % of impedance bandwidth for |S11| better than -7.5 dB. This covers the working frequency band (470-862 MHz) of DVB-T system. The radiation pattern of the proposed antenna is omnidirectional across the desired operating frequency band. Details of the proposed antenna designs and experimental results of the constructed prototypes are presented and discussed.
