摘要

在之前的天花板天线的基础上,本文提出了一种双极化天花板天线。它由一个垂直偏振单元和一个水平偏振单元组成。垂直偏振单元是单极的变换,看起来像中间包。所述水平极化单元包括基板环上的四个偶极子。这两个单元组成了一个嵌套结构。该双极化顶置天线的阻抗带宽范围为2.3 ~ 2.7 GHz,覆盖TD-SCDMA频段(2.3 ~ 2.4 GHz)。由于天线的对称结构,天线在方位角上向外辐射出全向图案。

A broadband dual-polarization ceiling-mounted antenna with a nesting structure
A dual-polarized ceiling-mounted antenna, based on previous ceiling-mounted antennas is proposed in this letter. It consists of one vertical polarization unit and one horizontal polarization unit. The vertical polarization unit is a transformation of a monople, looking like a tundish. And the horizontal polarization unit comprises of four dipoles on a substrate ring. The two units compose a nesting structure. The impedance bandwidth of this dual-polarization ceiling-mounted antenna ranges from 2.3 to 2.7 GHz, covering TD-SCDMA band (2.3 GHz to 2.4 GHz). And due to the symmetrical structures, the antenna radiates omnidirectional patterns in azimuth.
