Frequency reconfigurable wideband compact dual-polarized magneto-electric dipole

Abstract

In this paper, a novel wideband frequency reconfigurable compact dual-polarized magneto-electric dipole is presented. The antenna has two operation modes and cover an ultra-wideband operation frequency from 1.5 to 2.8 GHz and from 2.5 to 4.6 GHz with a Standing Wave Ratio (SWR) <3. RF PIN diodes are placed on the antenna structure and used as switches to select different operation modes. Moreover, in the lower operation band adding a capacitive loading allows to miniaturize the antenna height to 0.1λ.
