An Improved Broadband Multi-layer Dual-polarized Antenna for UAV Radars

摘要

In this paper, an improved wideband multilayer dual-polarized antenna fed by stripline coupling slots is proposed at Ku-band. The horizontal polarization(HP) of the antenna is realized by the coupling of driven patch to the parasitic patch. The vertical polarization(VP) is excited by H-shape slots on both sides ground of stripline, which is in turn coupled by a stripline feeder. Some metallized vias are used to achieve good impedance matching between H-shaped slots and stripline feeder. Simulation results show that the actual operating bandwidth of the antenna two polarizations can be greater than 4GHZ.
