A reconfigurable compact antenna for DVBH application

Abstract- This paper presents a novel design of compact antenna that covers the frequency from 470MHz to 770MHz (DVBH application). The design is based on a monopole antenna and a reconfigurable matching network. The antenna has a dimension of 28.4x21.6x17.5 mm
³
. It is installed into a device with a volume of 115x74x16 mm
³
. The matching network consists of switches, capacitors and inductors, and can be reconfigured to eight schemes. Accordingly, the antenna can be dynamically tuned to eight different frequency bands within the whole band. These separate bands combine to cover the ISDB-T frequency range, with good antenna performance.
