This communication presents a reconfigurable antenna capable of independently reconfiguring the operating frequency, radiation pattern and polarization. A switched grid of small metallic patches, known as pixel surface, is used as a parasitic layer to prov ...
Recently, a technique called beam-space MIMO has been demonstrated as an effective approach for transmitting multiple signals while using a single RF-chain. In this work, we present novel design considerations and a compact antenna solution to stimulate th ...

A new compact coplanar-fed antenna suitable for polarization diversity in ultra-wideband applications is presented. The antenna consists of two identical monopoles which are printed on a low-loss substrate with 3 mm spacing and positioned perpendicular to ...

In this paper, we present an experiment-and simulation-based study to evaluate the use of full duplex (FD) as a potential mode in practical IEEE 802.11 networks. To enable the study, we designed a 20-MHz multiantenna orthogonal frequency-division-multiplex ...
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 ...
We present an experiment-based characterization of passive suppression and active self-interference cancellation mechanisms in full-duplex wireless communication systems. In particular, we consider passive suppression due to antenna separation at the same ...
This article considers the exploitation of parasitic antenna arrays in multi-user (MU) wireless communication systems by using their adaptive beamforming capabilities in order to improve the average system throughput. The use of parasitic arrays and especi ...
We show that the public experiment held in Venice by Tamburini et al and reported in 2012 New J. Phys. 14 033001 can be regarded as a particular implementation of multiple-input-multiple-output (MIMO) communications and, therefore, has no advantages over e ...

This paper presents a coplanar-fed antenna designed to operate close to the human body in the 2.45 GHz Industrial Scientific Medical (ISM) band. The antenna matching is studied in free space and in body proximity. Two models of the human arm, with flat and ...
