基于整机的5G核心射频器件天线的仿真评估

双极化微带天线具有频率复用、收发一体、极化分集、体积小、易加工和易集成等优点受到广泛研究和运用.传统上常用的微带天线采用的同轴馈电和微带线馈电,而目前双极化微带天线的馈电方式多采用缝隙耦合,运用两层介质板的微带缝隙耦合天线一层基板包含辐射元件,一层基板包含馈电网络,通过缝隙耦合传输能量.天线辐射贴片和馈电结构不在同一介质层,天线的谐振器也增加到两个:缝隙、贴片,这样就使得馈电结构优化方便、可以获得高的隔离度和增加频率带宽.随对缝隙耦合天线的深入研究,H型缝隙耦合天线,双极化宽带缝隙耦合微带阵列天线等具有良好的性能.

Radiation Characteristics of Rectangular Patch Antennas with an Array of Pins

The patch antennas with an array of pins （pin array patch antennas） with excellent radiation characteristics are investigated for various substrate thicknesses. The radiation in the horizontal plane of a pin array patch antenna is very small compared to that of a conventional patch antenna. And the increase of forward radiation and the decrease of backward radiation of a pin array patch antenna are obtained than those conventional one＇s. Also the half-power beamwidth of E -plane radiation pattern of a pin array patch antenna is narrower compared to that of the conventional so that the directivity is improved.
