Fractus TVNow™ internal mobile TV antennas – DVB-H antenna and ISDB-H antenna - reduce handset size by up to 25%

Mobile TV handsets create a range of antenna design challenges because of interference from overlapping DVB-H and GSM frequencies and the differing effects of users' hand and body positions when they are viewing the TV screen, when it is usually held towards the lap, or making phone calls. Early mobile TV handsets used the headphone cable as the mobile TV antenna, rendering the device useless without the headphones.

Fractus was the first telecoms antenna developer to announce a suite of DVB-H and ISDB-H internal mobile TV antenna solutions for all three mobile TV frequencies; VHF, UHF and 1.6GHz L-band. Fractus TVNow™ antennas include a fully customised internal antenna for VHF, and a customised and integrated solution for UHF and 1.6GHz L-band. The range also includes a modular and compact SMT (surface mounted technology) antenna for UHF and 1.6GHz L-band, with a size of just 40 x 4.8 x 5mm3, that can reduce DVB-H handset platform size by as much as 25%.

This means that a fully customised mobile TV antenna can be discretely housed within the handset, no matter what the DVB-H frequency, helping OEMs and ODMs reduce product development costs and time to market, and enabling greatly improved design options. The TVNow range also includes ISDB-H antennas, ensuring all mobile TV requirements are covered by the range.
