Abstract :
A simple wideband and dual-polarized array is proposed. It is comprised of connected crossed hollow bowtie antennas. The element design can achieve an impedance bandwidth about 57% (from 1.5 to 2.7GHz). The 3dB gain bandwidth of the element is nearly 70% (from 1.35 to 2.75GHz). Dual polarization can be realized with a the good isolation (-25dB) between different polarization ports. A Γ - shape feed structure is used to excite the antenna. A 5×5 array is modeled and simulated. The impedance bandwidth of this array is similar as the element, and the 3dB gain bandwidth of this array is 63% (from 1.4 to 2.7GHz). The radiation pattern is stable and unidirectional within the gain bandwidth.
