“…As the antenna is used for reception only, some mismatch may be acceptable. Especially, if the LNA is designed together with the antenna so that the LNA adapts to the impedance of the antenna, some mismatch or rather non-50 ohm impedance is then acceptable [7]. In [2] it was presented that the return loss matching between 1 and 2 dB yields approximately the realized gain between -5 and -2.5 dBi, which is at least 2 dB more than required in the DVB-H specification.…”

The current trend in mobile terminals is an increasing number of systems. The volume occupied by the antennas of the radio systems is becoming more and more problematic and new low-volume antenna solutions are needed. Since the EMC shielding and the ground plane operate as the main radiating structure especially below 1 GHz, a very small antenna structure can be achieved by using a direct feed, i.e. galvanically inducing currents on the surface of the chassis. The feed can be placed over an impedance discontinuity, e.g. formed by a slot. Using this approach, an antenna structure for a small handheld digital television (DVB-H) receiver is presented. The antenna gain exceeds the specification by a 4-dB margin. The introduced antenna structure can also be used for multi-system terminals.

“…reception with compliance to the MBRAI specification [1], targeting category b2 (pocketable digital TV receivers) and c (handheld portable convergence terminal). The particularity of those categories is the low gain of the antenna, about 10 dBi, due to the small size antenna connected to the devices ( where l is the wavelength) [2]. As a consequence, TV signals are weak compared to conventional TV receivers as shown in Fig.…”

This paper describes fully integrated RF IC sub-system of a DVB-T/H receiver intended for Mobile TV reception. The architecture of the RF IC has been designed to be compliant with the category b2 & c of the MBRAI 1 specification developed for the introduction of TV into existing mobile phone. The coexistence with GSM transceivers has been taken into account to establish the complete link budget from UHF antenna down to the Digital Front-end. A broadband LNA has been designed for an overall IC noise figure of 3.9 dB. The IIP3 is 5 dBm while 25 dBm RF IIP2 has been measured. A 5th order low pass filter has been implemented for adjacent channel suppression. The total power consumption is 150 mW in continuous mode. Thanks to a new broadband synthesizer architecture using a single VCO, the occupied silicon area is 2.2 mm 2 in a 0.25 m BiCMOS technology.

Integration of DVB-H into mobile terminals is of high topical interest. In many cases the physical size of the terminal and antenna is too small to allow for coverage of the full DVB-H band. This paper presents an electrically tunable DVB-H antenna which covers the frequency range 462 ... 696 MHz with a return loss of at least 7 dB and remarkable radiation efficiency, using a volume of only 6 cm3. Emphasis is on the problem of coexistence of DVB-H with EGSM 900 operation which arises from the nonlinearity of the tuning element for the DVB-H antenna. A novel combination of non-linearity mitigation techniques is proposed to overcome the problem.
