A Novel Design of Radiation Pattern-Reconfigurable Antenna System for Millimeter-Wave 5G Applications

Published in: IEEE Transactions on Antennas and Propagation

Nov 06, 2019

/ Ismail Ben Mabrouk / muath alhasan Mourad Nedil Tayeb Denidni Abdel Sebak

In this paper, a novel design of dielectric resonator antenna (DRA) with a reconfigurable radiation pattern capability is presented. Reconfigurability in the azimuth plane is achieved by symmetrically placing six electromagnetic bandgap (EBG) sectors around the DRA. Each sector is composed of twenty-six circular shaped mushroom-like EBG unit cell. In order to achieve 360 degrees pattern reconfigurability with a minimum number of diodes, a network of metallic veins printed on a conductor-...

A survey dataset on determinants of administrative corruption

Published in: Data in Brief

Nov 01, 2019

/ Salem Al Jundi

This data article describes a survey dataset on administrative corruption and its main determinants (culture, organizational culture, political instability, and institutional weakness) in addition to social class. Prior research was consulted to determine indicators of the constructs of administrative corruption. Each construct has four reflective indicators while social class has formative variables. All items are measured using a seven-point Likert scale and semantic differential scale types....

Interaction Between Environmental Kuznet Curve and Urban Environment Transition Hypotheses in Malaysia

Published in: International Journal of Energy Economics and Policy

Oct 20, 2019

Hussain Ali Bekhet Nor Salwati Othman / Tahira Yasmin

The aim of this paper is to examine the interconnection between the environmental Kuznet curve (EKC) and urban environment transition hypotheses in the Malaysian economy. Economic growth, CO2 emissions, energy consumption, financial development (FD), urbanization variables for the 1971-2013 period, F-bound tests, and multivariate Granger causality methods are used. The long-run relationships among the above series of variables are examined. Also, the findings confirm the existence of an invere...
