Summary:
A digital video broadcasting-handheld (DVB-H) is a new standard for delivering broadcast television to mobile terminal, and it was officially endorsed by the Europe Union in 2008. In recent days, mobile TV for handheld device has become an important issue and especially DVB-H is planning to be serviced in Europe as well as many countries in the world. The DVB-H standard is designed to operate in UHF bands IV, V (470-862 MHz) and L band (1452-1492 MHz) [1]. The antenna size for DVB-H is too large to be assembled in mobile equipment because a quarter of a wavelength of the UHF band in vacuum is about 90-160mm. According to DVB-H implementation guidelines, an antenna gain of -10 dBi at 470 MHz to -7 dBi at 702 MHz is required [1]. Recently some various intennas for DVB-H have been developed including design of the novel DVB-H antenna for mobile handheld terminal [2], internal antenna with modified monopole type for DVB-H applications [3], and compact broadband planar antenna for DVB-H applications [4]. In [2], the DVB-H antenna as a coupled element is confined only to the folder type mobile devices. The proposed antenna in reference [3] is also difficult to apply compact devices, because the antenna has very restrictive relationship between radiator and ground as monopole type. In this paper, we have presented a broadband planar inverted F-shape antenna (BPIFA) with matching circuit which can be easily embedded into side faces of the PMP and optimized for the DVB-H frequency bands of 470-862 MHz and 1452-1492 MHz. We used a planar inverted F-shaped radiator with wide arm to diversify the current paths. Also, we used a simple matching circuit which is composed of the lumped elements (an inductor and two capacitors) for broadband operations over the proposed DVB-H frequency band. The antenna was designed, fabricated, and measured in the case of PMP platform (i-station U43, Digital-Cube) with case (εr=3.2). It is possible to miniaturize since the antenna is compact. The radiation patterns of proposed antenna are omni-directional which is the same as conventional monopole antenna. The proposed antenna has wideband and satisfies UHF and L bands for DVB-H service.
