On the Feasibility of Wireless Energy Transfer Using Massive Antenna Arrays

open access: yes, 2016
We illustrate potential benefits of using massive antenna arrays for wireless energy transfer (WET). Specifically, we analyze probability of outage in WET over fading channels when a base station (BS) with multiple antennas beamforms energy to a wireless

Dealing with Interference in Distributed Large-scale MIMO Systems: A Statistical Approach [PDF]

open access: yes, 2014
This paper considers the problem of interference control through the use of second-order statistics in massive MIMO multi-cell networks. We consider both the cases of co-located massive arrays and large-scale distributed antenna settings.

Pattern Synthesis of Dual-band Shared Aperture Interleaved Linear Antenna Arrays [PDF]

open access: yes, 2014
This paper presents an approach to improve the efficiency of an array aperture by interleaving two different arrays in the same aperture area. Two sub-arrays working at different frequencies are interleaved in the same linear aperture area. The available

Directional emission of light from a nano-optical Yagi-Uda antenna

open access: yes, 2009
The plasmon resonance of metal nanoparticles can enhance and direct light from optical emitters in much the same way that radio frequency (RF) antennas enhance and direct the emission from electrical circuits.

Synthesis of linear antenna arrays [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 1976
Synthesis of antenna arrays employing the L_{2} -norm as well as the L_{\infty} -norm is discussed. The approximation in the L_{\infty} -norm is obtained making use of Lawson's algorithm. A general iterative perturbation technique has been evolved for pattern synthesis for the case when the antenna currents alone are varied as web as for the case when ...

Circularly Polarized Antenna Array Fed by Air-Bridge Free CPW-Slotline Network

open access: yesInternational Journal of Antennas and Propagation, 2017
A novel design of 1×2 and 2×2 circularly polarized (CP) microstrip patch antenna arrays is presented in this paper. The two CP antenna arrays are fed by sequentially rotated coplanar waveguide (CPW) to slotline networks and are processed on 1 mm thick ...

Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna

open access: yes, 2017
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

A high‐power, high‐isolation, dual‐polarised planar phased array antenna

open access: yesIET Microwaves, Antennas & Propagation
A high‐power, high‐isolation, dual‐polarised planar phased array antenna is presented. Based on a multi‐layer microstrip structure, two sets of polarisation ports are fed through orthogonal slot coupling, achieving high isolation and low cross ...
