Global LTE antenna reference design for smartphones supports MIMO

July 10, 2012 // By Jean-Pierre Joosting
Antenova Ltd., has released an LTE antenna reference design for smartphones which covers the global LTE bands. The extremely wideband and efficient antenna design overcomes the difficulty of covering all the LTE frequency bands without the use of switches or tunable active components, resulting in a significantly lower cost LTE MIMO (Multiple-In-Multiple-Out) antenna system for smartphones.

The A10453 is a fixed frequency LTE antenna that covers LTE 700, GSM850, GSM900, DCS1800, PCS1900, WCDMA2100, LTE B7 (2500-2690 MHz), LTE B38 (2570-2620 MHz), and LTE B40 (2300 – 2400 MHz) bands.

When utilized in MIMO configuration, the antenna system provides total efficiencies of more than 50% over all bands with an average efficiency over all bands of 61%, as well as isolation between 2 antenna elements of below -10 dB over all bands, return loss better than 6 dB over all frequency bands and better than 10 dB on LTE B7, and superior hand and head performance.

The A10453 can be realized using flexi or LDS on a plastic carrier and customized to fit specific mechanical IDs.

The A10453 LTE antenna is a low profile 6-mm height internal corner mount antenna utilizing Antenova’s innovative antenna technology, which covers the five cellular bands plus the LTE bands. The LTE antenna can be used as a single element for SISO (Single-In-Single-Out) applications or in pairs in a symmetric configuration for a MIMO system. Optimal performance is achieved when two A10453 antennas in a symmetric pair configuration are mounted along the short edge of the PCB in smartphone applications. A USB connector can also be fitted between the two antenna elements without affecting the performance.
