Abstract

This paper proposes a novel low-profile broadband printed antenna. It consists of two FR4 dielectric substrates, each printed on one side with different radiation units. The upper radiation element is a $⊔$ -shaped bent dipole, while the lower is a $⊓$ -shaped bent dipole. There is no overlap between the two in the vertical direction. Additionally, the shape of each arm is altered to enhance the radiation performance. A stepped impedance converter makes the connection between the feedline and the arms to improve the broadband characteristics of the antenna. A gap is left between the top and bottom plates to introduce an air layer to enhance the antenna radiation performance. The antenna has been subjected to manufacturing and testing, and the results obtained are consistent with those predicted by the simulation. The return loss of the proposed antenna is less than −10 dB in the frequency range of 2.69–3.22 GHz, and it exhibits an ultra-low profile.

s波段超低轮廓宽带印刷间隙和垂直非对称印刷偶极子天线

本文提出了一种新型的低轮廓宽带印刷天线。它由两个FR4介电基板组成，每个基板在一侧印刷不同的辐射单元。上面的辐射元是一个* * $\bigsqcup $形状的弯曲偶极子，而下面的辐射元是一个* * $\sqcap $形状的弯曲偶极子。两者在垂直方向上没有重叠。此外，每个手臂的形状被改变，以提高辐射性能。在馈线和臂之间采用阶跃阻抗变换器连接，以提高天线的宽带特性。在顶板和底板之间留有空隙，引入空气层以增强天线的辐射性能。对该天线进行了制造和测试，得到的结果与仿真预测的结果一致。该天线在2.69 ~ 3.22 GHz频率范围内回波损耗小于−10 dB，且具有超低轮廓。
