本文提出了一种基于两个交叉磁电偶极子的降低双极化单向宽带天线高度的新颖方法。小型化技术在于在垂直板之间添加电容负载。辐射元件的高度减小到0.1wr0，其中λ0是驻波比为2.5的最低工作频率处的波长，对应于37.5%的折减系数。从1.6千兆赫到3.1千兆赫，测量的输入阻抗带宽为%，驻波比为2.5。
In this paper, an original method to reduce the height of a dual-polarized unidirectional wideband antenna based on two crossed magneto-electric dipoles is proposed. The miniaturization technique consists in adding a capacitive load between vertical plates. The height of the radiating element is reduced to 0.1λ0, where λ0 is the wavelength at the lowest operation frequency for a Standing Wave Ratio (SWR) <2.5, which corresponds to a reduction factor of 37.5%. The measured input impedance bandwidth is 64% from 1.6 GHz to 3.1 GHz with a SWR <2.5.
