A MATLAB Interface for Analyzing Conformal Arrays Composed of Polarized Heterogeneous Elements
(Institute of Electrical and Electronics Engineers, 2011-10)
[Abstract] As an extension and improvement of a previous work, this paper presents a graphical interface designed with MATLAB®, which is capable of representing both the spatial and electrical configurations of a conformal ...
Time Modulated Arrays: from their Origin to Their Utilization in Wireless Communication Systems
(M D P I AG, 2017-03-14)
[Abstract] Time-modulated arrays (TMAs) are electromagnetic systems whose radiated power pattern is controlled by the application of variable-width periodical pulses to the individual elements. The nonlinear nature of the ...
A MATLAB Tool for Visualizing the 3D Polar Power Patterns and Excitations of Conformal Arrays
(Institute of Electrical and Electronics Engineers, 2010-08)
[Abstract] This paper describes the implementation of a MATLAB® tool to plot the three-dimensional polar radiation diagram generated by a conformal antenna array. A related tool has also been developed for visualizing the ...
Time-modulated array beamforming with periodic stair-step pulses
(Elsevier, 2020-01)
[Abstract]: Time-modulated arrays (TMAs) are able to improve the side-lobe level of the radiation pattern at the fundamental mode but cannot steer the beam at such a mode towards a given direction. Beam-steering is possible ...
Time-Modulated Phased Array Controlled With Nonideal Bipolar Squared Periodic Sequences
(Institute of Electrical and Electronics Engineers, 2019-02)
[Abstract]: Bipolar (±1) sequences with no zero state suit particularly well for safeguarding the switched feeding network efficiency when applied to time-modulated arrays. During the zero state of a conventional time-modulating ...
Dual-Signal Transmission Using RF Precoding and Analog Beamforming With TMAs
(IEEE, 2018-06)
[Absctract]: Time-modulated arrays (TMAs) receiving beamforming provide a noteworthy hardware simplicity given the ability of this multi-antenna technique to transform spatial diversity into frequency diversity. However, ...

(Institute of Electrical and Electronics Engineers, 2018)
[Abstract]: Time-modulated arrays (TMAs) receiving beamforming provide a noteworthy hardware simplicity given the ability of this multi-antenna technique to transform spatial diversity into frequency diversity. However, ...
Performance Analysis of Time-Modulated Arrays for the Angle Diversity Reception of Digital Linear Modulated Signals
(Institute of Electrical and Electronics Engineers, 2017)
[Abstract]: Diversity occurs whenever several copies of the same transmitted signal arrive at a receiver. Such a situation allows for improving the performance of a wireless communication system transmitting over a radio ...
Impact of Time-Modulated Arrays on the BER of Linear Digital Modulations
(Taylor & Francis, 2015-08-21)
[Abstract] Time modulation provides a simple way to control the power radiation pattern of an antenna array. By appropriately selecting the parameters of a Time-Modulated Array (TMA) it is possible to obtain a reconfigurable ...
