Benefits of Handset Antenna Diversity for UMTS
نویسندگان
چکیده
The benefits of receiver antenna diversity in a Universal Mobile Telecommunications System (UMTS) handset were studied. Two different channel models were used, one an extension to the 3GPP multipath fading channels and the other based on 3-D scattering and angular weighting via a practically realisable antenna configuration. Simulated performance benefits arising from the use of a second receive antenna with coded UMTS data are compared with the benefits for uncoded data. Plots of coded block-error-rate (BLER) against uncoded physical bit-error-rate (BER) for cases with and without receive antenna diversity show improvements in block error rate up to 1 dB better than predicted by the change in physical bit-error-rate.

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets
A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...
