Dual-Band MIMO Internal Antenna Optimizes 802.11n System Performance

This new ‘N’ generation of 802.11 provides much greater data throughput rates than the previous 802.11a/b/g standards. Few dual-band antennas are currently available for 802.11n MIMO applications; however, Laird Technologies’ new internal antenna expands and broadens its MIMO antenna product portfolio.

Designed using Laird Technologies’ proprietary RF optimization tools, the SM24513P3 dual band MIMO internal antenna packs three high-performance antennas onto one PC board assembly for internal connection to a MIMO radio. Integration into a housing containing a MIMO radio is made easy by micro coax cables that are an integral part of the antenna assembly.

The size, gain, and beam pattern of the antenna makes it ideal for indoor WLAN applications in either the 2.4-2.5 GHz or 5.1-5.9 GHz band. This allows OEMs and systems integrators to offer a high-performance and cost-effective built-in MIMO antenna solution for many common WLAN applications, including hospitals, schools and campuses, transport terminals, and other business enterprises.

Radiation patterns are uniform and symmetrical, providing high-level signal density into defined coverage zones, greatly enhancing the performance of 802.11n systems. The dual-band frequency coverage means this antenna can be deployed with any MIMO radio operating in the 2.4-2.5 GHz and 5.1-5.9 GHz bands.

The SM24513P3 operates over a temperature range of -30° to +65°C and incorporates polarization diversity that increases data throughput in multipath environments.

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

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