Pulse UWB antennas enable high-speed wireless connection between devices.

Focus EDL has a new family of ultrawideband (UWB) high-gain low-profile internal planar antennas for high-speed short-range datacommunications equipment.

Produced by Pulse, these UWB antennas are available in sizes that are optimised for applications currently using the UWB spectrum and create opportunities for new applications in the UWB spectrum.

Current applications include laptops, M2M devices, PDAs, smart phones and high-definition multimedia interfaces (HDMIs) operating on the full 3.1-10.3GHz UWB spectrum.

Pulse's UWB antennas enable high-speed wireless connection between devices.

The Pulse UWB family includes the W3540, W3541 and W3542 planar antennas.

The antennas are compact, lightweight, and at a height of just 0.8mm, they are among the thinnest antennas on the market.

All versions have a minimum of -10dB return loss.

Dimensions of the W3540 are 10.2 x 13.35 x 0.8mm, its weight is 0.27g, and its ground clearance under the antenna is 20.0 x 13.5mm.

They are best for applications of 2.7 to 8.2GHz, 3.1 to 4.95GHz UWB low band, and 6.9 to 8.5GHz UWB high band.

For applications of 4.5 to 14.0GHz, the W3541 is 6.5 x 8.0 x 0.8mm, with a weight of 0.082g, and a ground clearance under the antenna of 10.0 x 8.5mm.

The W3542 is 5.0 x 6.0 x 0.8mm, has a weight of 0.046g, a ground clearance under the antenna of 8.1 x 6.5mm, and is best for applications in the 6.3 to 12.0GHz range.

These UWB antennas provide omnidirectional radiation to assure full 360-degree coverage, have a specially shaped patch-type radiator to enable expanded signal coverage, and deliver constant gain across the operation band for secure signal uniformity.

Each antenna has an impedance of 50ohm and operates at temperatures from -40 to +85C.

They are all fully surface mount compatible and RoHS compliant.
