New over-the-air (OTA) measurement technology is wanted for quantitative testing of modern wireless devices for use in multipath. We show that the reverberation chamber emulates a rich isotropic multipath (RIMP), making it an extreme reference enviro

Publikováno v: IEEE Antennas and Wireless Propagation Letters. 10:1201-1204

We present a simple theoretical model for the throughput data rate of a wireless LTE device including the improvements of data rate due to diversity in frequency (OFDM) and spatial domains (MIMO) under frequency selective fading. The model is based o

In Situ Measurement of UHF Wearable Antenna Radiation Efficiency Using a Reverberation Chamber

Autor: William Scanlon, C. Walker, Gareth A. Conway, Charlie Orlenius

Publikováno v: IEEE Antennas and Wireless Propagation Letters. 7:271-274

The radiation efficiency and resonance frequency of five compact antennas worn by nine individual test subjects was measured at 2.45 GHz in a reverberation chamber. The results show that, despite significant differences in body mass, wearable antenna
