L-Shaped Trigger - 4 and 5-Port Under-Dash Antenna Family for Increased RF Performance in Automotive and IoT Applications

Trigger - 4 and 5-Port Under-Dash Antenna family

The Trigger under-dash telematics antenna family from Laird Connectivity is designed for discrete or covert mounting underneath vehicle dashboards. Offering cellular 3G/4G/5G/ISM/CBRS, Wi-Fi, and GNSS in a unique format, these L-shaped new devices from the company shows significant performance improvements and as much as a 20% increase in efficiency over candy bar style antennas already up in the market. Available in both four-port and five-port options, each antenna in the family comes with vertical and horizontal cellular radiating elements within the same antenna. 


The integration of orthogonally oriented elements in the Trigger under-dash telematics antenna family helps in improving both signals received power and quality due to superior de-correlation of the MIMO pair of cellular ports. Moreover, the reduced gain pattern nulls/ripple and more omnidirectional gain from the vertical dipole element make these devices all the more beneficial.


The antennas can be covertly mounted alongside or over bulky non-metallic objects such as vent ducts.  They can be mounted closer to vehicle routers and gateways that are usually sited under dashboards, under seats, or in the vehicle's trunk. This avoids complex antenna installations where roof or trunk lids might need to be drilled to install an external antenna.


When mounted closer to the gateway, these antennas require shorter cables which results in increased RF performance. The devices in the family can be used in both dense urban environments as well as remote locations where signals may be either impeded or weak as these devices offer optimized across-horizon performance and excellent around-the-vehicle coverage. 


The VP of Strategic Business Development, Laird Connectivity, Bill Steinike said: "The Trigger antenna family is a vast improvement for in-vehicle multi-band connectivity over existing technologies. Our team took on a significant challenge with this development to enable a new concept design to provide a market-leading solution."
