    Carrier aggregation compatible MIMO antenna for LTE handset
    (Electromagnetics Academy, 2017) Rasilainen K.; Lehtovuori A.; Boussada A.; Viikari V.
    This paper proposes a two-element LTE MIMO handset antenna with physically different main and diversity antennas. The performance of the design is studied theoretically and experimentally. The investigated design utilises physically different main and diversity antennas to improve especially the low-band MIMO performance. A Combined Parasitic-coupled, Aperture-Matched (CPAM) antenna is used as the main antenna, and the diversity antenna is a simple Capacitive Coupling Element (CCE) design. The antenna covers the LTE bands from 698–960 MHz and 1710–2690 MHz with fixed matching circuits suitable for low-band (LB) Carrier Aggregation (CA). Measured total efficiency of the antennas is from ?3 to ?6dB and ?2 to ?5 dB at the low and high bands, respectively. In the MIMO case, envelope correlation coefficient (ECC) and multiplexing efficiency ((image found)mux) are studied also from measurements. © 2017, Electromagnetics Academy. All rights reserved.
