Summary:
Recently, many countries are switching their terrestrial television broadcasting from analog to digital [1] and the demand of TV reception increases for mobile terminals, such as mobile phones and notebook PCs. Antennas for these devices are required to be compact, operate at the broadband covering the broadcast frequencies. Some antennas have been developed for the purpose but they are large in size or have only narrow bandwidth [2]-[4]. A compact loop-type antenna with wide bandwidth has been proposed but its performance is not presented for installation on real devices [5]. In this paper, we will propose a compact antenna for digital terrestrial television reception. The antenna is based on a planar inverted-F antenna (PIFA) and is made of films. It is designed for an installation on the back of the liquid crystal display (LCD) of a notebook PC. The antenna is installed into the PC by deforming a planar film antenna and has a compact size of 84 x 46 x 6 mm3. Experiment demonstrates that the antenna works at a frequency range of 470?890 MHz, which covers bands in ISDB-T, ATSC and DVB-T, and radiates with efficiency higher than 50%.
