Laird releases dual-band external antennas

A Laird Technologies product story

Edited by the Electronicstalk editorial team Feb 27, 2009

Laird Technologies has announced two dual-band MIMO external antennas: the S245112PT Directional and the S24517PT Sector.

Both antennas are designed to enhance the latest generation of Wireless LAN (WLAN) systems and make use of MIMO technology in which multiple wireless transmitters and receivers operate simultaneously.

This 'N' generation of 802.11 technology provides much greater data throughput rates than the previous 802.11a/b/g standards.

The S245112PT directional panel antenna and the S24517PT directional sector antenna are enclosed in a low-profile UV-resistant polycarbonate weatherproof radome housing.

Both models have three MIMO antenna elements, each of which is connected to the WLAN access point via a low-loss, coax pigtail.

The high gain and narrow beam width of the S245112PT antenna makes it ideal for point-to-point and long-range outdoor WLAN applications.

The gain and beam width of the S24517PT makes it ideal for general purpose indoor and outdoor applications.

Radiation patterns are uniform and symmetrical, providing high-level signal density in defined coverage zones, greatly enhancing the performance of 802.11n systems.

The dual-band frequency coverage means these antennas can be deployed with any MIMO radio operating in the 2.4-2.5GHz and 5.1-5.9GHz bands.

Both antennas offer high performance in a small housing, operate over a temperature range of -30 to +65C, incorporate polarisation diversity that increases data throughput in multipath environments, and hold the IP-67 water and dust seal rating.

Laird Technologies' multi-element antennas are designed for a high degree of internal RF isolation between each of their antenna elements - a critical factor in MIMO systems.

The size, gain and beam patterns allow OEMs and system integrators to offer high-performance and cost-effective MIMO systems for many common WLAN applications, including hospitals, schools, transport terminals, and business enterprises.

These RoHS-compliant antennas are available with a wide choice of connector and board configurations, as well as in customised versions to fit a variety of OEM housings.
