Wide‐angle scanning phased array using wide‐beamwidth dielectric resonator antenna with miniaturised radiator

open access: yesElectronics Letters, 2022
A wide‐beamwidth dielectric resonator antenna with small radiator is used to design a wide‐angle scanning phased array. The proposed dielectric resonator antenna element uses concave structure for wide‐beamwidth, and the metal patches on the top of the ...

A new multipath mitigation method for GNSS receivers based on antenna array [PDF]

open access: yes, 2012
the potential of small antenna array for multipath mitigation in GNSS systems is considered in this paper. To discriminate the different incoming signals (Line of sight and multipaths), a new implementation of the well known SAGE algorithm is proposed ...

Circuits and Systems for Wireless Concurrent Communication [PDF]

open access: yes, 2009
Concurrency is a special kind of analog circuit parallelism that uses a single circuit with necessary bandwidth to process multiple signals at the same time. Concurrent radios offer a higher data rate and improved system diversity.

Robust approaches to remote calibration of a transmitting array [PDF]

open access: yes, 2010
We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna.

Hybrid Parasitic Linear Array Antenna for Fine Beamsteering Applications

open access: yesIEEE Access, 2021
This paper presents an antenna that utilizes two beam steering techniques in concert in order to improve the antenna gain and steering resolution. Phased array steering is employed to achieve coarse resolution beam steering while parasitic steering is ...
