The reverberation chamber (RC) has traditionally been used for electromagnetic
compatibility tests. About two decade ago, it found application in various over-the-air (OTA) …

Early work on carbon nanotube (CNT) antennas indicated that their performance could not
match that of metals such as copper. However, recent improvements in fluid phase CNT …

The emerging machine‐to‐machine (M2M) communications and Internet‐of‐things
techniques bring new challenges in over‐the‐air (OTA) tests. The inexpensive M2M device …

To optimize the design of a high-sensitivity receiver, it is valuable to be able to assign noise
budget contributions to various parts of the system. The system noise and aperture efficiency …

We assess the potential error in measurements of the power transfer function corresponding
to a reverberation chamber set-up when different antenna types are used for the reference …

Reverberation chambers (RCs) have become a popular testing facility in antenna efficiency
measurements. Unlike the standard reference antenna method, the non-reference antenna …

We provide total radiated power measurements at millimeter-wave frequencies using a
reverberation chamber and a power-calibrated vector network analyzer capable of …

When reverberation chambers are loaded to increase the coherence bandwidth for
modulated-signal measurements, a secondary effect is decreased spatial uniformity. We …

The effect of a user's proximity on wireless device performance is critical to test the device
under realistic conditions. In this article, we propose and demonstrate an improved …

The need for accurate efficiency measurements at high frequencies of large form-factor
devices is ever increasing. In this work, the potential of performing antenna efficiency …
