Pulse, a Technitrol company, has launched a new family of DVB-H, MediaFLO and DMB-S antennas that the company said are so thin and light they enable mobile TV applications to be incorporated into small mobile handsets. The antennas are suitable to all form factors such as bar, monoblock and slide and meet the high-performance mobile TV standards.

The company's DVB-H EU 470-750 MHz antenna is one of the thinnest mobile TV antennas available at 45-by-6-by-7mm and 1.35g. It is designed to meet tough durability requirements and requires only a few screws and an RF cable to connect to the handset. It has a coaxial cable feed with I-PEX connector. This performance is guaranteed by integrating a matching network to the antenna element. The matching network integration secures performance in all handset form factors and when using different antenna installation sites. The antenna radiators and matching network are designed to reduce reception from interfering signals, an essential feature in all multiradio applications where strong signals, such as GSM, are constantly interfering with the DVB-H receiver.

Compact and low-profile, the 719MHz MediaFLO antenna is designed for very low frequencies. The unique antenna pattern enables optimal antenna miniaturization without compromising performance. The antenna size is 10-by-3.2-by-4mm and weighs 0.6g. As high as 2dBi gain and 70 percent radiation efficiency can be reached. The MediaFLO antenna is built on ceramic technology which provides selectivity, isolation and immunity to user hand-effect.

The 2.6GHz DMB-S ceramic chip antenna is just 3.2-by-1.6-by-1.1mm and weighs 0.03g. The use of a miniature standard PCB footprint offers easy implementation on any handset or device while maintaining the performance. The same antenna structure is also suitable for other L-band mobile TV standards, as in 1.6GHz and 1.4GHz applications. It is SMD-compatible, a competitive catalog product and available in tape-and-reel packaging.

These DVB-H, MediaFLO and DMB-S antennas meet most mobile TV standards and are compatible with terrestrial and satellite solutions. They are RoHS-compliant.
