Array-Fed Partially Reflective Surface Antenna With Independent Scanning and Beamwidth Dynamic Control

Julien Perruisseau-Carrier, Tomislav Debogovic

In this communication we present a concept of a partially reflective surface (PRS) antenna capable of independent beam-scanning and beamwidth dynamic control. The beamwidth is controlled by reconfiguring the PRS reflectivity via embedded varactor diodes, w ...

Multiple antenna

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

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 ...

Towards compact and frequency-tunable antenna solutions for MIMO transmission with a single RF chain

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

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 ...

On the selection of radiating elements for compact indoor massive-MIMO base stations

Julien Perruisseau-Carrier

Massive-multiple input multiple output (MIMO) was recently proposed as a key solution for improving the performance of multi-user MIMO in future cellular generations. The main paradigm in this novel MIMO technique is to use a very large number of antenna e ...

A Multipath Sparse Beamfroming Method

Hervé Bourlard, Volkan Cevher, Afsaneh Asaei

A novel formulation of beamforming is proposed for acquisition of the signals in reverberant acoustic clutter of interferences and noise. We derive the beamforming methods which incorporate the sparsity structure pertained to the acoustic source distributi ...

On Self-interference Suppression Methods for Low-complexity Full-duplex MIMO

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Konstantinos Alexandris

Full-duplex wireless communication offers improved spectral efﬁciency, as well as more efﬁcient relaying and medium access, but requires suppression of self-interference. In this paper we analyze the existing methods for active RF suppression and use the ” ...

Graphene Antennas: Can Integration and Reconfigurability Compensate for the Loss?

Julien Perruisseau-Carrier, Michele Tamagnone

In this opening presentation we will first recall the main characteristics of graphene conductivity and electromagnetic wave propagation on graphene-based structures. Based on these observations and different graphene antenna simulations from microwave to ...
