Reconfigurable Pico-cell Antenna Array for Indoor Coverage in GSM 900 Band [PDF]

open access: yesRadioengineering, 2009
This paper proposes a simple antenna array based on three stacked shorted patches aimed to be used as GSM (900 MHz) indoor base station antenna. Three same linearly polarized stacked patches are set in three orthogonal planes in space forming pyramid ...

The performance of Taguchi’s T-method with binary bat algorithm based on great value priority binarization for prediction [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
Taguchi’s T-method is a predictive modeling technique under the Mahalanobis-Taguchi system that is based on the regression principle and robust quality engineering elements to predict future state or unknown outcomes.

MIMU Optimal Redundant Structure and Signal Fusion Algorithm Based on a Non-Orthogonal MEMS Inertial Sensor Array

open access: yesMicromachines, 2023
A micro-inertial measurement unit (MIMU) is usually used to sense the angular rate and acceleration of the flight carrier. In this study, multiple MEMS gyroscopes were used to form a spatial non-orthogonal array to construct a redundant MIMU system, and ...

ORTHOGONAL ARRAYS OBTAINED BY ARRAY SUBTRACTION

open access: yesJournal of Applied Analysis & Computation, 2021
Summary: In this paper, by using the orthogonal decompositions of projection matrices, a new general approach is proposed to construct asymmetrical OAs, namely array subtraction, the operation of which is not the usual subtraction but it is interesting since many so called atoms of asymmetrical OAs can be obtained by the array subtraction.

Design of Nonuniformly Spaced Antenna Arrays Using Orthogonal Coefficients Equating Method [PDF]

open access: yesRadioengineering, 2022
Orthogonal Coefficients Equating (OCE) method as an analytic method is proposed to synthesize nonuniformly spaced antenna arrays to have array factors nearly equal to that of a previously designed uniformly spaced antenna arrays.
