The miniature antenna measures 33x10.5x7 mm3 and supports the DVB-H standard on the UHF (470 – 750 MHz) frequency band. The myMobile TV handset is just 97x47x23 mm3 in size, with a 56mm x 40mm swivel impressive QVGA colour screen.

The vast majority of mobile TV handsets currently on the market use an external antenna, while the few using internal
antennas are much bulkier than SAGEM’s new design.  Fractus also overcame other RF challenges as the GSM and DVB-H frequency
bands used in the phone intersect, potentially creating a major interference issue. 

“Simply put - DVB-H is the single greatest challenge facing handset designers today as consumers are not willing to
compromise on the aesthetic of their device in return for new features,” said Alfonso Sanz, Fractus Lead Engineer,
Products & Services Division. 
“Most people could be forgiven for thinking that the external mobile antenna had been relegated to the history books,
but mobile TV has brought about its reappearance.”

To save space, the antenna for the myMobileTV handset was designed using Fractus’ patented fractal antenna technologies,
allowing Sagem Communication to create a smaller phone platform than what has been achieved by other mobile TV

Mobile television raises major interference challenges caused by overlapping DVB-H and GSM frequencies and also from the
differing body position when holding the phone in front of the body (watching TV) as opposed to the typical position
against the head when making a call. Sagem’s myMobileTV posed additional antenna design challenges because its swivel
QVGA colour screen enables the handset to take multiple form factors - each of which demands meticulous RF planning to
ensure consistently high reception.

Fractus provided SAGEM with complete antenna design, development, support, testing, manufacturing and approval services
to ensure the customised antenna was as effective as possible within the handset, while respecting SAGEM’s mechanical
and design requirements. 

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, in late 2006. The Fractus TVNowTM range
of antennas for Mobile TV was commended for the GSM Association’s Global Mobile Awards 2007.
