This article describes a reconfigurable monopole liquid antenna array, suitable for wireless communications in the UHF band, focusing on obtaining and controlling notch radiation directions. Two different implementations are being studied, at the beginning three collinear monopoles placed over a ground plane and then, five monopoles over a ground plane placed in such a manner as to form a cross. By replacing the parasitic elements with cylinders filled with conductive fluids and also surrounding the driven element, it is possible it is possible to change at will the whole antenna's layout and to control both the maximum directivity angle over the azimuth and the resonant frequency, filtering interfered channels and background noise. © 2016 Wiley Periodicals, Inc.
