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 mm3. It is installed into a device with a volume of 115x74x16 mm3. The matching network consists of switches, capacitors and inductors, and can...
This paper presents a novel design of a compact varactor-tuned PIFA antenna for ISDB-T (terrestrial integrated services digital broadcasting) application. This design is based on capacitor loaded planar inverted-F antenna (PIFA) structure, and its resonance frequency can be electrically controlled so that wideband operation is achieved. A tuning circuit which consists of a varactor diode is introduced...
