Compact antennas take diversity onboard

High-performance ceramic diversity antennas enable high datarate transmission despite their size.

Although small enough to fit in mobile terminals such as new-generation multimedia phones, notebook computers, PDAs, media players, WLAN routers, data cards and other wireless devices, a new range of high-performance ceramic diversity antennas from Solid State Supplies enable high datarate transmission despite their size.

Available in six frequencies, 850MHz, 900MHz, 1.8GHz, 1.9GHz, 2.1GHz and 2.4GHz, the lightweight omnidirectional antennas are based on standard diversity platforms, and feature low profiles and compact sizes.

Their ceramic composition provides a high degree of signal immunity, which enables them to be placed close to other antennas for high-performance diversity operation in small devices.

Using diversity antennas in close proximity enables them to be switched within microseconds if one antenna experiences noise, providing improved signal quality with fewer dropouts.

The antennas are RoHS compliant and are compatible with lead-free, surface mount processes.

Sizes are 10 x 3.2 x 2mm for the 1.8, 1.9 and 2.1GHz models, 10 x 3.2 x 4mm for the 850 and 900MHz devices, and 3.2 x 1.6 x 1.1mm for the 2.4GHz version.

According to John Macmichael from Solid State Supplies: "Diversity solutions will play an important role in allowing mobile networks and terminal devices to offer the highest possible data transmission rates in all operating conditions".

"These ceramic diversity antennas allow consumers to purchase the small, fashionable electronic devices they prefer and still get a clear signal and fast datarates".

Antennas are available in tape-and-reel packaging and lead-time is six to eight weeks.
