3-feed antenna for operator-independent LTE global roaming

December 07, 2011 // By Julien Happich
Pulse Electronics announced a 3-feed antenna that enables operator-independent global roaming capability for LTE mobile devices. Compatible with EPCOS RF front-end module (FEM) technology, it is the only antenna that has been proven to support 16 frequency bands, including Japanese frequency bands in the 1.5 GHz range, claims the manufacturer.

The device optimizes performance in 700-960MHz, 1.42-1.5GHz, 1710-2170MHz, and 2.3-2.7GHz bands and supports HSPA and LTE inter-band carrier aggregation band combinations defined in 3GPP releases 9 and 10. In a simulation with an EPCOS FEM under development, it provides +2dB performance improvement at around 2 and 2.6GHz, eases WLAN and LTE coexistence, and enables global use of a device for TDD and FDD. Because the signals from the RF front end are separated into three antenna feed points, this antenna provides the best performance on the market. It allows for seamless global LTE roaming and increased data download rates. The antenna measures 50x13x7mm, its performance results in improved battery life and fewer dropped calls. The 3-feed antenna can be used as a standalone antenna or as one antenna in diversity/MIMO applications. It is 3D-fitted by using LDS manufacturing technology and is also available on flex. Ground clearance is 9mm, but it can be optimized for use with a particular RF module. Speaker integration with the frame is possible. The RoHS compliant unit comes packaged in trays.
