A double integral operation is required to obtain gain in an array antenna in general, and only an omnidirectional antenna is represented in a closed form. In this letter, as a result of radio-wave propagation research, a closed-form expression that can be applied to a small dipole antenna or a half-wavelength dipole antenna is shown by using an equation applicable to spatial correlation in a three-dimensional multipath environment. In addition, the maximum gain characteristics of the half-wavelength dipole element linear array antenna are analyzed using the equation.

偶极子元件紧密放置的阵列天线的最大增益


阵列天线一般需要进行二重积分运算才能获得增益，只有全向天线以闭合形式表示。在这封信中，作为无线电波传播研究的结果，通过使用适用于三维空间相关性的方程，示出了可应用于小型偶极子天线或半波长偶极子天线的封闭式表达式。多路径环境。此外，利用该方程分析了半波长偶极子线阵天线的最大增益特性。
