Cost-effective OTA performance testing of MIMO-enabled LTE devices

Overview of LTE MIMO OTA Throughput Testing in Reverberation Chambers

It is not possible to do direct tests to find the best LTE multi-antenna configuration for optimizing antenna diversity gain, antenna MIMO capacity or device throughput with the traditional antenna measurement method, i.e. an anechoic chamber. Of the two alternatives for making direct measurements, i.e. drive tests and the reverberation chamber, the reverberation chamber offers many advantages....

Two-Channel Method for OTA Performance Measurements of MIMO-Enabled Devices White paper

Characterization of Small Antennas & Wireless Devices for MIMO Systems in Rich Isotropic Multipath & Random Line-of-Sight

The current thesis is about over-the-air (OTA) performance characterization of wireless terminals in rich isotropic multipath (RIMP) environment as well as in pure line-of-sight (LOS) environment while not ignoring the random positions and orientations of the mobile terminals due to randomness of the user. The latest mobile wireless terminals such as iPhone and iPad can be used in any random po...

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...

Survey on MIMO antennas for mobile and compensating user’s induced loss

An analysis of MIMO antenna system in the development of LTE (Long Term Evolution) terminal and the compensation of user’s induced loss is presented in this paper. MIMO wireless systems have antenna arrays at both the transmitter and receiver terminals. Multiple input multiple output (MIMO) technology has been regarded as a practical approach to achieve significant increase of wireless channel ...
