Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...
A multi-input, multi-output antenna comprises an electrically conductive body, generally symmetrical about a plane of symmetry. An active port (Feed point) is located on the plane, a first parasitic port (1) is located on one side of the plane, and a secon ...
The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters is presented. The scattered fiel ...

Antennas are an important element of Wireless Body Area Network equipments, as the quality of the antenna and its coupling to the channel will be a key component of the quality of the overall link. Indeed, the antenna and its interaction with the body of t ...
This article reviews the family of Ultra Wideband (UWB) antenna radiation efficiency measurement methods com- monly known as the UWB Wheeler cap. Measurement results of one UWB and two narrowband antennas are compared with the recently introduced source-st ...
This study reports an experimental study of the system fidelity factor (SFF) of ultra-wideband wireless body area network antennas in an on-body environment. This study also investigates the influence in the SFF because of the antenna polarisation with res ...
The Wireless Body Area Network (WBAN) has become an important part of the wireless communication world in the past decade leading to the need for efficient antennas for In-, On- and Off-Body links. The design of such antennas depends critically on the unde ...
