3-feed antenna provides operator-independent global roaming for LTE devices
The 3-feed antenna optimizes performance in 700 to 960 MHz, 1.42 to 1.5 GHz, 1710 to 2170 MHz, and 2.3 to 2.7 GHz 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 +2 dB performance improvement at around 2 and 2.6 GHz, 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 claims to provide the best performance on the market. It allows for seamless global LTE roaming and increased data download rates.
Targeting high-end smartphones, the antenna has a compact size with maximum dimensions of 50- x 13- x 7-mm, which includes volume to integrate components like speakers, etc. The exceptional antenna performance results in improved battery life and fewer dropped calls. This RF platform, comprising the EPCOS FEM and the Pulse Electronics antenna, enhances the entire smartphone ecosystem.
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 9-mm, but it can be optimized for use with a particular RF module. Speaker integration with the frame is possible. The 3-feed antenna is based on proven antenna design and matching technology and is usable for single band or carrier aggregation mode of operation.
This antenna is RoHS compliant and comes packaged in trays. The antenna design is custom-made to customer specifications.
