摘要

本文提出了一种具有简单机载馈电网络的宽带印刷贴片偶极天线。所提出的天线由两个偶极辐射器、一条传输线和一个带芯片巴伦的车载馈电网络组成。偶极辐射器印刷在基板上，辐射器的边缘被截断，以形成具有宽阻抗匹配特性的六边形。芯片平衡-不平衡变换器嵌入RO4003C印刷电路板（PCB）中，以激励具有180°相位差的每个散热器的差分馈电。使用CST Studio全电磁软件工具对所提出的天线进行了优化，并在消声室中进行了制造和测量。反射系数低于-10 dB时的测量分数带宽为79.5%，所提出的天线在3.5 GHz时的测量增益为7.1 dBi。

Design of a Wideband Printed Patch Dipole Antenna with a Balanced On-Board Feeding Network

This paper proposes a wideband printed patch dipole antenna with a simple on-board feeding network. The proposed antenna is composed of two dipole radiators, a transmission line, and an on-board feeding network with a chip balun. The dipole radiators are printed on a substrate, and the edges of the radiators are truncated to create a hexagonal shape with wide impedance-matching characteristics. The chip balun is embedded in an RO4003C printed circuit board (PCB) to excite differential feeding to each radiator with a 180° phase difference. The proposed antenna is optimized using a CST Studio full electromagnetic software tool, and it is fabricated and measured in an anechoic chamber. The measured fractional bandwidth for the reflection coefficient below –10 dB is 79.5%, and the proposed antenna has a measured gain of 7.1 dBi at 3.5 GHz.
